[Solved] How to not print integer when its value is zero? [closed]

by


Since you’re using C++, why not use stringstream to build your buffer in pieces:

#include <cstdio>
#include <sstream>
#include <string>

using namespace std;

int main() {
    string s1 = "s1";
    string s2 = "s2";
    string s3 = "s3";
    int x = 0;

    stringstream ss;
    ss << s1 << "," << s2 << "," << s3;
    if (x != 0)
        ss << "," << x;
    ss << " " << endl;

    // Don't do this!  See link below
    //const char* c = ss.str().c_str();

    string result = ss.str();
    const char* c = result.c_str();

    printf("Result: '%s'\n", c);
    getchar();
    return 0;
}
