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
    uint32_t val = 0;
    uint32_t  temp=0;
    
    val = reg&0x7C00;
    val= val>>10;
    
    if(val<31)
    {
        val=val+1;
        
        val = val<<10;
        
       temp = reg & ~(0x00007C00);
      
        temp|=val;
    }
    else{
        return reg;
    }

    return temp;
}

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