英文:
Power function [pow()] always giving a ZERO as result
问题
Power function always giving a zero(0) as result no matter the input.
我学习了幂函数，但无论输入什么都会得到零(0)作为结果。
#include <stdio.h>#include <math.h>int main(){int A, B;int C = pow(A, B);printf("要查找的幂请输入 A 和 B 的值\n");printf("请输入 A 的值：\n");scanf("%d", &A);printf("请输入 B 的值：\n");scanf("%d", &B);printf("A 和 B 的幂是：%d", C);return 0;}
不要翻译的部分已保留。
英文:
Power function always giving a zero(0) as result no matter the input.
I am learning the power function, but it doesn't work.please help.
#include <stdio.h>#include <math.h>int main(){    int A,B;    int C=pow(A,B);    printf("To find power please enter values of A and B \n");    printf( "Please enter value of A: \n");    scanf("%d",&A);    printf("Please enter value of B: \n");    scanf("%d",&B);    printf("The power of A and B is : %d",C);    return 0;}

You're setting the value of C before you assign the A and C values.
将int C = pow(a, b);放在运行printf("The power of A and B is : %d",C);之前。
完整的代码
#include <stdio.h>#include <math.h>int main(){int A, B;printf("要找到幂，请输入A和B的值\n");printf("请输入A的值：\n");scanf("%d", &A);printf("请输入B的值：\n");scanf("%d", &B);int C = pow(A, B);printf("A和B的幂是：%d", C);return 0;}
标签"powershell"似乎是随机的，应该将标签设置为您正在使用的编程语言。
英文:
You're setting the value of C before you assign the A and C values.
Put int C = pow(a, b); right before you run printf("The power of A and B is : %d",C);
Complete code
#include <stdio.h>#include <math.h>int main(){int A, B;printf("To find power please enter values of A and B \n");printf("Please enter value of A: \n");scanf("%d", &A);printf("Please enter value of B: \n");scanf("%d", &B);int C = pow(A, B);printf("The power of A and B is : %d", C);return 0;}
The tag powershell seems random, you should have the tag set to the language that you're using.

Int C=pow(A,B);
printf("A 和 B 的幂是：%d",C);
基本上是将它从上面移到下面。
而且它奏效了！
英文:
I just now moved the
Int C=pow(A,B);
line just before
printf("The power of A and B is : %d",C);
Basically moved it from top to bottom.
And it worked!
