Little Endian to Big Endian

Code

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

uint32_t convert_endian(uint32_t value) {
    uint32_t temp=0;
    
    for(int i=0;i<4;i++)
    {
    temp=(temp<<(8))| ((value>>(8*i))& 0xff);
    }

    return temp;
}

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