Clear Specific Bits in a 32-bit Register

Code

#include <stdio.h>
#include <stdint.h>

uint32_t clear_bits(uint32_t reg, uint8_t pos, uint8_t len) {
    // Your code here
    uint32_t temp = 0;
    for(int i = pos; i<(pos+len); i++)
    {
        temp |= (1<<i);
    }
    return (reg & (~temp));
}

int main() {
    uint32_t reg;
    uint8_t pos, len;
    scanf("%u %hhu %hhu", &reg, &pos, &len);
    printf("%u", clear_bits(reg, pos, len));
    return 0;
}
