Little Endian to Big Endian

Code

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

uint32_t convert_endian(uint32_t value) {
    uint32_t bige0 = (value & 0x000000FF)<<24;
    uint32_t bige1 = (value & 0x0000FF00)<<8;
    uint32_t bige2 = (value & 0x00FF0000)>>8;
    uint32_t bige3 = (value & 0xFF000000)>>24;
    return bige0 | bige1 | bige2 | bige3;
}

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