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 val=0;
    val=reg&(((1<<5)-1)<<10);
    val=val>>10;
    if(val<31)
    {
        val++;
    }
    reg&=~(((1<<5)-1)<<10);
    reg|=(val<<10);
    return reg;
}

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