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 final_val=0;
    uint32_t temp =0;
    temp = reg&0x7C00;
    // return temp;
    temp = temp>>10;
    // return temp;
    if(temp<31){
        temp++;
    }
    // return temp;
    temp = temp<<10;
    reg = reg & (~(0x7C00));
    return reg | temp ;
}

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