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;

    temp  = (reg>>10)&0x0000001F;

    if(temp<31)
    {
        temp++;
    }

    temp = (temp)<<10;

    reg = reg & 0xFFFF03FF;
    reg = reg | temp;
    

    return reg;
}

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