Example

int main(int argc, char* argv[]) { int num = (argc>1) ? 1: 0; return (num==1) ? 0 : 1; }

Solution

The ternary operator can be confusing, using if/else is more readable. int main(int argc, char* argv[]) { int num; if(argc>1){ num = 1; } else{ num = 0; } if(num==1){ return  0; } return 1; }
