Little Endian to Big Endian

Code

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

uint32_t convert_endian(uint32_t value) {
    // Write logic to swap bytes
    uint32_t bigendian = 0, temp;
    for(uint8_t i=0; i<4; i++)
    {
        bigendian <<= 8;
        temp = (value >> i*8) & 0xFF;
        bigendian |= temp;
    }
    return bigendian;
}

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