一个玩笑，c++调用python

python文件:

#!/usr/bin/python
#python.py
print 'python:hello world'

shell文件

#!/usr/bin/sh
#shell.sh
#chmod +x shell.sh
echo shell:hello world
python python.py

cpp文件

//callpython.cpp
#include <iostream>
#include <stdlib.h>
using namespace std;
int main () {
    cout << "cpp:hello world" << endl;
    system("./shell.sh");
    return 0;
}

编译运行:

#g++ callpython.cpp -o callpython
#./callpython

运行结果:

cpp:hello world
shell:hello world
python:hello world
