Set Multiple Bits in 8-bit Register

Code

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

uint8_t set_range(uint8_t reg, uint8_t start, uint8_t end) {
    // Your code here
        for(int i=start; i<=end; i++){
                reg |= (1<<i);
                    }
                        return reg;
                        }

                        int main() {
                            uint8_t reg, start, end;
                                scanf("%hhu %hhu %hhu", &reg, &start, &end);
                                    printf("%u", set_range(reg, start, end));
                                        return 0;
                                        }
