#include <stdio.h> #include <stdint.h> uint8_t set_bit(uint8_t reg, uint8_t pos) { reg |= (1<<pos); return reg; } int main() { uint8_t reg, pos; scanf("%hhu %hhu", ®, &pos); // Accept register value and position uint8_t result = set_bit(reg, pos); printf("%u", result); // Output the result as an integer return 0; }
Solving ApproachU can set a bit by doing Bitwise OR operation with that bit. U can do it by left shifting 1 to the required postion.
