C Variables

Declare typed values.

#include <stdio.h>
int main(void) {
  int score = 91;
  printf("%d\n", score);
  return 0;
}

Output

Explanation

C variables have explicit types. int stores an integer, while double stores a floating point value. printf writes formatted output.

What happens	State after step	Output so far
Allocate an int named score and initialize it to 91.	`score = 91`	—
%d formats the integer; \n ends the line.	`score = 91`	91
Return zero to signal successful completion.	`score = 91`	91
