The role of return in C language

The role of return in C language

The role of return in C language is to shift the program flow from the called function to the calling function , and bring the value of the expression back to the calling function to realize the return of the function value. The return can be accompanied by a return value, specified by the parameter after return. If the function without a return value is of empty type, it is represented by void.

Code example

int sum(int i,int j)
{
  return i+j;
  printf ("123456");
}
main()
{
  int a=10,b=11,c;
  c=sum(a,b);
  printf("%d",c);
}

The output of the program is: 21
