Little Endian to Big Endian

Code

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

uint32_t convert_endian(uint32_t value) {

    uint32_t temp1,temp2;

    //0x12345678 → 0x78563412

    // Write logic to swap bytes

    temp1 = value & 0xFF;
    temp2 = (value >> 24) & 0xFF;
    value &= ~(0xFF);
    value &= ~(0xFF000000);
    value |= temp2 << 0;
    value |= temp1 << 24;

    temp1 = (value >> 8) & 0xFF;
    temp2 = (value >> 16) & 0xFF;
    value &= ~(0xFF00);
    value &= ~(0xFF0000);
    
    value |= temp1 << 16;
    value |= temp2 << 8;

    
    return value;

}

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