Little Endian to Big Endian

Code

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

typedef union {    
uint32_t value;    
uint8_t bytes[4];
} integerUnion;

uint32_t convert_endian(uint32_t value) {
    // Write logic to swap bytes
    uint32_t convert = 0;
    integerUnion n;
    n.value = value;
    for(int i = 0;i<4;i++)
    {
        convert <<= 8;
        convert |= n.bytes[i];
    }
    return convert;
}

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