Extract and Modify Field in a 32-bit Register

Code

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

uint32_t update_register(uint32_t reg) {
    // Your logic here
    uint8_t mask = (1U<<5)-1;
    uint32_t value = (reg & (mask<<10))>>10;
    if(value<31) value = value+1;

    reg&=~(mask<<10);
    reg|=value<<10;
    return reg;
}

int main() {
    uint32_t reg;
    scanf("%u", &reg);
    uint32_t updated = update_register(reg);
    printf("%u", updated);
    return 0;
}
