Little Endian to Big Endian

Code

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

uint32_t convert_endian(uint32_t value) {
    // Write logic to swap bytes //0x12345678
    uint32_t val1 = (value >> 24) & 0x000000FF; // 0x00000012
    uint32_t val2 = (value >> 8) & 0x0000FF00; //0x00003400
    uint32_t val3 = (value << 8) & 0x00FF0000; //0x00560000
    uint32_t val4 = (value << 24) & 0xFF000000; //0x78000000
    value = val1|val2|val3|val4;
    return value;
}

int main() {
    uint32_t val;
    scanf("%u", &val);
    printf("%u", convert_endian(val));
    return 0;
