Power function is calculated using the times multiple i.e. 5n is 5*5*5… n times. For this function, to work properly without using multiplication(*) and division(/) operators we will use nested loops that add the numbers n number of time.
Example
#include <iostream>
using namespace std;
int main() {
int a= 4 , b = 2;
if (b == 0)
cout<<"The answer is"<<1;
int answer = a;
int increment = a;
int i, j;
for(i = 1; i < b; i++) {
for(j = 1; j < a; j++) {
answer += increment;
}
increment = answer;
}
cout<<"The answer is "<<answer;
return 0;
}Output
The answer is 16
