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 00000000 00000000 01000100 00000000
    uint8_t val = (reg>>10)& 0x1F; //extract
    if(val <31)
    val++;                //modify

    reg = (reg & (0xFFFF83ff))| (val<<10);

    return reg;
}

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