c++ - Power function in a loop -

i need writing power function. so, need write porogramm, output table 1 10 in power in loop. not using pow or exp example of output:

0^0 == 1 1^1 == 1 2^2 == 4 3^3 == 27 4^4 == 256 (and on, to) 10^10 == 10000000000 

not using cmath (no pow or exp)

for example:

e.g. power( 3.0, 5 ) return 243 because 3*3*3*3*3 243 e.g. power( 173, 0 ) return 1 because number raised power of 0 1.

i did simple loop, have no idea how insert power formula in it. thinking while loop

#include <iostream> #include <string> using namespace std;   int main(){      int number = 0, tot;      (int table = 0; table < 10; table++)     {         tot = number * table;         cout << tot << endl;         number++;     }     } 

this recursive function can calculate value raised integer power

double power(double base, unsigned int exp) {     if (exp == 0)     {         return 1.0;     }     else     {         return base * power(base, exp - 1);     } } 

an iterative method be

double power(double base, unsigned int exp) {     double product = 1.0;     (unsigned int = 0; < exp; ++i)     {         product *= base;     }     return product; } 

you can test either method like

int main() {     std::cout << power(5, 3); } 

output
