Question

How to get min and max values of all data types in C

Answer 1

#include <stdio.h>
#include <limits.h>

int main() {
    printf("CHAR_MIN  = %+d\n", CHAR_MIN);
    printf("CHAR_MAX  = %+d\n", CHAR_MAX);
    printf("SCHAR_MIN = %+d\n", SCHAR_MIN);
    printf("SCHAR_MAX = %+d\n", SCHAR_MAX);
    printf("UCHAR_MAX = %u\n\n", UCHAR_MAX);

    printf("SHRT_MIN  = %+d\n", SHRT_MIN);
    printf("SHRT_MAX  = %+d\n", SHRT_MAX);
    printf("USHRT_MAX = %u\n\n",  USHRT_MAX);

    printf("INT_MIN  = %+d\n", INT_MIN);
    printf("INT_MAX  = %+d\n", INT_MAX);
    printf("UINT_MAX = %u\n\n",  UINT_MAX);

    printf("LONG_MIN  = %+ld\n", LONG_MIN);
    printf("LONG_MAX  = %+ld\n", LONG_MAX);
    printf("ULONG_MAX = %lu\n\n",  ULONG_MAX);

    printf("LLONG_MIN  = %+lld\n", LLONG_MIN);
    printf("LLONG_MAX  = %+lld\n", LLONG_MAX);
    printf("ULLONG_MAX = %llu\n\n",  ULLONG_MAX);

    return 0;
}
