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 l_bit=(reg>>10)&0x1F;
    if(l_bit<31){
        l_bit++;
    reg &= ~(0x1F<<10);
    reg|=(l_bit<<10);}
    // Your logic here
    return reg;
}

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

Solving Approach

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