Set Specific Bits in a 32-bit Register

peCode

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

uint32_t set_bits(uint32_t reg, uint8_t pos, uint8_t len) {
    // Your code goes here
    for (uint32_t i = pos ; i < pos + len ; i++)
    {
        reg |=(1 << i); 
    }
    return reg;
}

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

Solving Approach

We use a for loop and set the bits accordingly 

 

for (uint32_t set_INseries = pos ; set_INseries  < pos + len ; set_INseries ++)

{

    reg | = (1 << set_INseries) ; // Set a continuous no of bits
}
