Interested in programming and the physical sciences. I primarily use C and C++ but also sometimes use Swift and Java.

Do not forget to check for and report errors:

#include <stdio.h>
int main(void) {
    return puts("Hello, World!") < 0;
}

Do not add pointless if statements to functions that have the effect of returning a condition:

// if (condition)
//     return true;
// else
//     return false;
return condition;
