how to do this question.
Write a program that computer X^N where x and N are positive integers. The program must inform the user that N must be positive if the user enters a negative value.
Write a program that computer X^N where x and N are positive integers. The program must inform the user that N must be positive if the user enters a negative value.
#include<stdio.h>
#include<math.h>
void main()
{
float X,N;
double S;
printf("please input X,N:");
scanf("%f,%f",&X,&N);
if(N<0)
{
printf("N must be positive!");
}
else
{
S=pow(X,N);
printf("result:%f\n",S);
}
}
写程序，计算机χ ^ n其中X和N的正整数。该提示必须告知用户， n必须是正的，如果用户输入一个负值。
就是计算幂。如果输入的是负数转换成整数，
这都不会？？OMG。你不如去死好了。
