Question

I have a structure that has 3 different types of values in it (char, float, int)…….I need to set everything to 0 at the beginning of the program. How do I do that?

Answer 1

 struct A
 {
   int a;
   char b;
   float c;
 };

struct A is an aggregate, built-in types initialized to 0. You can initialize to A in two ways:

//Class method pass to function
int main() 
{
  A a = {};      // initialize single A to 0
  A b = A();     // same effort
  A c[10] = {};  // initialize array to 0

  return 0;
}
