【项目】写代码的代码【完】
本项目实现写代码的代码，用于C++，实现了快速排序、二分查找、字符串匹配和for和if的配合。
if(!flag3) {//开头
fout << "#include <iostream>" << endl;
fout << "#include <fstream>" << endl;
fout << "#include <algorithm>" << endl;
fout << "#include <string>" << endl;
fout << "#include <string.h>" << endl;
fout << "#include <cstdlib>" << endl;

fout << " string b[10000];" << endl;
fout << " string temp;" << endl;
fout << " getline(fin, temp);" << endl;
fout << " temp += '\\0';" << endl;
bool flag4 = false;
for(int i = 0;temp[i] != '\0';++i) {
if(temp[i] == '\"' || temp[i] == 'f' || temp[i] == 'F' || temp[i] == 'i' || temp[i] == 'I' ) {
flag4 = true;
break;
}
}
if(!flag4) {//判断是字符串输入还是数字输入
fout << " int count = 0;" << endl;
fout << " bool flag = false;" << endl;
fout << " for(int i = 0;temp[i] != '\\0';++i) {" << endl;
fout << " if(temp[i] != ' '){" << endl;
fout << " b[count] += temp[i];" << endl;
fout << " }" << endl;
fout << " else if(temp[i] == ' ') {" << endl;
fout << " flag = true;" << endl;
fout << " }" << endl;
fout << " if(flag) {" << endl;
fout << " stream << b[count];" << endl;
fout << " stream >> a[count];" << endl;

fout << " ++count;" << endl;
fout << " flag = false;" << endl;
fout << " }" << endl;
fout << " }" << endl;
}
else {
}
}
这里是写入开头部分，通过flag的操作保证只会书写一次，并且判断是否为数字输入还是字符串输入。
flag3 = true;
int flag2 = -1;
for(int i = 0;temp[i] != '\0';++i) {//判断是哪种逻辑
if(temp[i] == '>') {
flag2 = 1;
break;
}
else if(temp[i] == '<') {
flag2 = 2;
break;
}
else if(temp[i] == 'l' || temp[i] == 'L') {
flag2 = 3;
search1 = temp[i + 10];
break;
}
else if(temp[i] == 'u' || temp[i] == 'U') {
flag2 = 4;
search2 = temp[i + 10];
break;
}
else if(temp[i] == 'b' || temp[i] == 'B') {
flag2 = 5;
search3 = temp[i + 12];
break;
}
else if(temp[i] == '\"') {
flag2 = 6;
break;
}
else if(temp[i] == 'f' || temp[i] == 'F' || temp[i] == 'i' || temp[i] == 'I' ) {
flag2 = 7;
break;
}
}
判断是哪种逻辑，是排序还是二分查找还是字符串匹配还是for和if的配合。
if(flag2 == 1) {//快速排序
fout << " sort(a, a + count, greater<int>());" << endl;
fout << " for(int i = 0;i < count;++i) {" << endl;
fout << " fout << a[i] << ' ';" << endl;
fout << " }" << endl;
fout << " fout << endl;" << endl;
}
else if(flag2 == 2) {
fout << " sort(a, a + count, less<int>());" << endl;
fout << " for(int i = 0;i < count;++i) {" << endl;
fout << " fout << a[i] << ' ';" << endl;
fout << " }" << endl;
fout << " fout << endl;" << endl;
}
这两个是快速排序的输出
else if(flag2 == 3) {//二分查找
fout << " int x = lower_bound(a, a + count, " << search1 << ") - a;" << endl;
fout << " fout << x << endl;" << endl;
}
else if(flag2 == 4) {
fout << " int y = upper_bound(a, a + count, " << search2 << ") - a;" << endl;
fout << " fout << y << endl;" << endl;
}
else if(flag2 == 5) {
fout << " bool z = binary_search(a, a + count, " << search3 << ");" << endl;
fout << " fout << z << endl;" << endl;
}
这三个是二分查找
else if(flag2 == 6) {//字符串匹配
fout << " string str;" << endl;
fout << " for(int i = 0;i < temp.length() - 1;++i) {" << endl;
fout << " str += temp[i];" << endl;
fout << " }" << endl;
fout << " str += '\\0';" << endl;
fout << " char str1[10000], str2[10000];" << endl;
fout << " int i;" << endl;
fout << " for(i = 0;temp[i] != '\\0';++i) {" << endl;
fout << " str1[i] = temp[i];" << endl;
fout << " }" << endl;
fout << " str1[i] = '\\0';" << endl;
fout << " for(i = 0;str[i] != '\\0';++i) {" << endl;
fout << " str2[i] = str[i];" << endl;
fout << " }" << endl;
fout << " str2[i] = '\\0';" << endl;
fout << " char* pos = strstr(str1, str2);" << endl;
fout << " fout << *pos << endl;" << endl;
}
这个是字符串匹配
else if(flag2 == 7) {//for和if的配合
int c = 0;
for(int i = 0;i < temp.length();++i) {
if(temp[i] == 'f' || temp[i] == 'F') {
for(int j = 0;j < c;++j) {
fout << " ";
}
fout << "for(;;) {" << endl;
i += 2;
++c;
}
else if(temp[i] == 'i' || temp[i] == 'I') {
for(int j = 0;j < c;++j) {
fout << " ";
}
fout << "if() {" << endl;
i += 1;
++c;
}
}
int sum = c - 1;
for(int i = 0;i < c;++i) {
for(int j = sum;j > 0;--j) {
fout << " ";
}
--sum;
fout << "}" << endl;
}
}
这个是for和if的配合
if(y == num3 - 1) {//结尾
fout << " fin.close();" << endl;
fout << " fout.close();" << endl;
fout << " return 0;" << endl;
fout << "}" << endl;
}
这个是输出结尾
int main(int argc, char** argv) {
fout.open("out.cpp");
fin1.open("code.txt");
fin2.open("in.txt");
flag3 = false;
count1 = 0;
num2 = 0;
num3 = 0;
num4 = 0;
for(num0 = 0;getline(fin2, a2[num0]);++num0){//读取文件
a2[num0] += '\0';
temp = a2[num0];
count2 = 0;
for(int i = 0;temp[i] != '\0';++i) {
if(temp[i] != ' '){
a3[count2] += temp[i];
++count2;
}
}
}
for(num = 0;getline(fin1, a1[num]);++num){//判断是哪一部分
a1[num] += '\0';
temp = a1[num];
flag = -1;
for(int i = 0;i < temp.length();++i) {
if(temp[i] == '#') {
flag = 0;
break;
}
else if(temp[i] == 'l' || temp[i] == 'L') {
flag = 2;
break;
}
else if(temp[i] == 'o' || temp[i] == 'O') {
flag = 3;
break;
}
}
if(flag == 0) {
continue;
}
else if(flag == 2) {
for(int i = 0;temp[i] != ':';++i) {
count1 = i;
}
++count1;
++count1;
for(;temp[count1] != '\0';++count1){
logic[num3] += temp[count1];
}
logic[num3]+= '\0';
++num3;
}
else if(flag == 3) {
for(int i = 0;temp[i] != ':';++i) {
count1 = i;
}
++count1;
++count1;
for(;temp[count1] != '\0';++count1){
output[num4] += temp[count1];
}
output[num4] += '\0';
++num4;
}
}
temp = output[0];
if(temp[0] == 'n' || temp[0] == 'N') {//对逻辑进行处理
out1();
}
else if(temp[0] == 'r' || temp[0] == 'R'){
for(int i = 0;i < num3;++i) {
temp = logic[i];
out2(i);
}
}
else {
out1();
}
fin1.close();
fin2.close();
fout.close();
return 0;
}
以上是主函数
if(temp[0] == 'n' || temp[0] == 'N') {//没有输出的情况
fout << "#include <iostream>" << endl;
fout << "using namespace std;" << endl;
fout << "int main() {" << endl;
fout << " return 0;" << endl;
fout << "}" << endl;
}
这个是处理没有输出的情况
else {//有输出的情况
fout << "#include <iostream>" << endl;
fout << "#include <fstream>" << endl;
fout << "using namespace std;" << endl;
fout << "int main() {" << endl;
fout << " ofstream fout;" << endl;
fout << " fout.open(\"o.txt\");" << endl;
fout << " fout << \"" << temp << "\";" << endl;
fout << " fout.close();" << endl;
fout << " return 0;" << endl;
fout << "}" << endl;
}
这个是处理有输出的情况
实际操作如图：
得到代码
运行结果如图：
这里提示数组数据最后要以空格结尾。
然后是快速排序和二分查找的配合：
实际操作如图：
得到代码
运行结果如图：
然后是字符串匹配：
得到代码
运行结果如图：
然后是for和if的配合：
编辑
得到代码：
#include <iostream> #include <fstream> #include <algorithm> #include <string> #include <string.h> #include <cstdlib> #include <ctime> #include <cmath> #include <sstream> using namespace std; int main() { srand(time(NULL)); ofstream fout; ifstream fin; stringstream stream; fout.open("o.txt"); fin.open("in.txt"); int a[10000]; string b[10000]; string temp; getline(fin, temp); temp += '\0'; for(;;) { if() { for(;;) { if() { for(;;) { } } } } } fin.close(); fout.close(); return 0; }
然后output还有none和有输出的情况，none我们直接选择输出空程序，有输出直接输出结果，不管逻辑。
none情况如图：
得到代码
有输出的情况如图：
得到代码：
#include <iostream>
#include <fstream>
using namespace std;
int main() {
ofstream fout;
fout.open("o.txt");
fout << "1 2 3 4
运行结果如图：
以上就是写代码的代码的全部内容了，希望能给各位C++的忠粉带来便利！
