Question

I want to know if the format of user defined function i wrote i.e return(xxx) is correct or not . Because when i compile my code, i have to enter the input 2 times.It might be a silly mistake because i just began learning C language ****MY CODE:****``

#include<stdio.h>
long cube(long x );
long input,answer;
int  main (void )
{
    printf("Enter a number:");
    scanf("%ld ",&input);
    answer = cube(input);
    printf(" The cube of %ld is %ld",input ,answer);
    return 0;
}
long cube(long x )
{
   return (x*x*x);
}

****ANswer****

#include <stdio.h>
long cube(long x);
long input, answer;
int main( void )
 {
 printf("Enter an integer value: ");
 scanf("%d", &input);
 answer = cube(input);
 printf("\nThe cube of %ld is %ld.\n", input, answer);
 return 0;
 }


 long cube(long x)
{
 long x_cubed;

 x_cubed = x * x * x;
 return x_cubed;
 }

删除＆＃39;％ld＆＃39;之后的空格它需要一个输入。根据你的代码， scanf（＆＃34;％ld＆＃39;＆amp; input）; 这里的编译器首先要为＆＃39;％ld＆＃39;然后它等待你在'％ld＆＃39;之后使用的空格。删除它然后它将在一次输入后进入下一步。你应该用，的scanf（＆＃34;％LD％＆＃34;，＆安培;输入）;
