How to subtract an element form every element of the array

Program Code

// How to subtract an element form every element of the array

#include<stdio.h> 
void main()
{
int array[10],n,num, i;
printf("Enter How many elemnts you want to insert in array: ");
scanf("%d",&n) ;
for(i= 0; i<n; i++)
{
   printf("array[%d]: ",i);	
  scanf("%d",&array[i]);
}
printf("Enter a number you want to subtract with: ");
scanf("%d",&num) ;

 subanumber(array,n,num);   // function calling
 
}

void subanumber(int array[],int size,int number)
{
    int i;
    for(i=0;i<size;i++)
    {
        array[i]-=number;
    }
    
    for(i=0; i<size; i++)
	{
      printf("%d ",array[i]);
	}
}

Output

Enter How many elemnts you want to insert in array: 5
array[0]: 4
array[1]: 4
array[2]: 4
array[3]: 4
array[4]: 4
Enter a number you want to subtract with: 2
2 2 2 2 2

How to learn from this program

First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.

Practice suggestion

After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
