Extract and Modify Field in a 32-bit Register

Code

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

uint32_t update_register(uint32_t reg) {
    uint32_t temp = 0;
    uint32_t conditions = (reg >> 10) & 0x1F;
    if(conditions < 31){
        conditions ++;
        temp = (reg & (~(0x1F << 10))) | (conditions << 10);
        return temp;
    }
    else{
        return reg;
    }
    
}

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