Question

I am working on a 32-bit system. When I try to print more than one 64 bit value in a single printf, then it cannot print any further (i.e. 2nd, 3rd, …) variable values.

example:

uint64_t a = 0x12345678;
uint64_t b = 0x87654321;
uint64_t c = 0x11111111;

printf("a is %llx & b is %llx & c is %llx",a,b,c);

Why can this printf not print all values?

I am modifying my question

printf("a is %x & b is %llx & c is %llx",a,b,c);

by doing this result is : a is 12345678 & b is 8765432100000000 & c is 1111111100000000

if i am not printing a’s value properly then why other’s value’s are gona change??

You need to use the correct format:

#include <stdio.h>
#include <stdlib.h>
#include <inttypes.h>

int main(void)
{
    uint64_t a = 0x12345678;
    uint64_t b = 0x87654321;
    uint64_t c = 0x11111111;

    printf("a is %#" PRIx64
            " & b is %#" PRIx64
            " & c is %#" PRIx64 "\n",
            a, b, c);
    return EXIT_SUCCESS;
}

Output:

a is 0x12345678 & b is 0x87654321 & c is 0x11111111
