Set the Bit in an 8-bit Register

Code

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

uint8_t set_bit(uint8_t reg, uint8_t pos) {
    // Set the bit at position 'pos' using OR
    return reg | (1 << pos);
}

int main() {
    uint8_t reg, pos;
    scanf("%hhu %hhu", &reg, &pos);  // Accept register value and position

    if (pos > 7) {  // Validate bit position for 8-bit register
        printf("Invalid bit position\n");
        return 1;
    }

    uint8_t result = set_bit(reg, pos);
    printf("%u\n", result);         // Output the result as an integer

    return 0;
}
