How to create short signed type for 64 32 16 and 8 bits variables in C

Answer 1

#include <stdio.h>

typedef signed long long I64;
typedef signed int       I32;
typedef signed short     I16;
typedef signed char      I8;


int main() {

    I64 n_64 = 2846528734673;
    I32 n_32 = 1194967295;
    I32 n_16 = 4846529;
    I32 n_8 =  186;

    printf("%I64d\n", n_64); // gcc
    printf("%d\n",    n_32);
    printf("%d\n",    n_16);
    printf("%d\n",    n_8);

    return 0;
}
