Question

How to use integer types from stdint.h in C

Answer 1

#include <stdio.h>
#include <stdint.h>

int main() {
    int8_t i8 = 127;
    int16_t i16 = 32767;
    int32_t i32 = 2147483647;
    int64_t i64 = 9223372036854775807;

    uint8_t ui8 = 255;
    uint16_t ui16 = 65535;
    uint32_t ui32 = 4294967295;
    uint64_t ui64 = 18446744073709551615;

    printf("%d\n", i8);
    printf("%d\n", i16);
    printf("%d\n", i32);
    printf("%I64u\n\n", i64);

    printf("%u\n", ui8);
    printf("%u\n", ui16);
    printf("%u\n", ui32);
    printf("%I64u\n", ui64);

    return 0;
}
