---

#include <iostream>

#include <cstring>

using namespace std;

int main(int argc, char* argv[], char* env[]) {

int i;

int pos;

int check=0;

char content[50];

if (argc != 2) {

cout << "Only input one parameter after program name" << endl;

} else {

for (i=0; env[i]!=0 && check==0; i++) {

pos = strcspn(env[i], "=");

if (strncmp(argv[1], env[i], pos) == 0) {

check = 1;

strcpy(content, env[i]+pos+1);

}

}

if (check==1)

cout << argv[1] << " = " << content << endl;

else

cout << argv[1] << " not found" << endl;

        }

    return 0;

}

Better now.
