[C language] power table of 3 generated by PTA 7-53

Enter a non negative integer n, Generate one 3 The power table of , Output 3^0~3^n Value . Power function calculation can be called 3 Power of .

Input format :

The input gives a nonnegative integer on one line n.

Output format :

Output in ascending order of power n+1 That's ok , The format of each line is “pow(3,i) = 3 Of i The value of the power ”. Ensure that the output data does not exceed the range of long integers .

sample input :

3

No blank lines at the end

sample output :

pow(3,0) = 1
pow(3,1) = 3
pow(3,2) = 9
pow(3,3) = 27

No blank lines at the end

pow(a,b) Is to seek a^b Function of . To use this function, you need to include math.h This header file

#include<stdio.h>
#include<math.h> 
int main(){
	
	int n;
	scanf("%d",&n) ;
	int i;
	for(i=0;i<=n;i++){
		int a=pow(3,i);
		printf("pow(3,%d) = %d\n",i,a);
	}
	
	return 0;
}
