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 b0,b1,b2,b3;
    b0 = (value & 0x000000FF) << 24;
    b1 = (value & 0x0000FF00) << 8;
    b2 = (value & 0x00FF0000) >> 8;
    b3 = (value & 0xFF000000) >> 24;

    return (b0|b1|b2|b3);
}

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