在这里,我们将编写两个 C 程序来查找两个数字的平均值(由用户输入)。
示例 1:编程以查找两个数字的平均值
#include <stdio.h>
int main()
{
int num1, num2;
float avg;
printf("Enter first number: ");
scanf("%d",&num1);
printf("Enter second number: ");
scanf("%d",&num2);
avg= (float)(num1+num2)/2;
//%.2f is used for displaying output upto two decimal places
printf("Average of %d and %d is: %.2f",num1,num2,avg);
return 0;
}
输出:
Enter first number: 12
Enter second number: 13
Average of 12 and 13 is: 12.50
示例 2:使用函数用于查找均值的程序
在这个程序中,我们创建了一个用户定义函数average()
来计算平均值。用户输入的数字在函数调用期间传递给该函数。
#include <stdio.h>
float average(int a, int b){
return (float)(a+b)/2;
}
int main()
{
int num1, num2;
float avg;
printf("Enter first number: ");
scanf("%d",&num1);
printf("Enter second number: ");
scanf("%d",&num2);
avg = average(num1, num2);
//%.2f is used for displaying output upto two decimal places
printf("Average of %d and %d is: %.2f",num1,num2,avg);
return 0;
}
输出:
Enter first number: 20
Enter second number: 13
Average of 20 and 13 is: 16.50
