C Exercises: Read 10 numbers and find their sum and average

C For Loop: Exercise-4 with Solution

Write a program in C to read 10 numbers from keyboard and find their sum and average.

Pictorial Presentation:

Read 10 numbers and find their sum and average

Sample Solution:

C Code:

#include <stdio.h>
void main()
{       
    int i,n,sum=0;
	float avg;
	printf("Input the 10 numbers : \n");
	for (i=1;i<=10;i++)
	{
                printf("Number-%d :",i);

		scanf("%d",&n);
		sum +=n;
	}
	avg=sum/10.0;
	printf("The sum of 10 no is : %d\nThe Average is : %f\n",sum,avg);
 
}

Sample Output:

Input the 10 numbers :                                                                                        
Number-1 :1                                                                                                   
Number-2 :2                                                                                                   
Number-3 :3                                                                                                   
Number-4 :4                                                                                                   
Number-5 :5                                                                                                   
Number-6 :6                                                                                                   
Number-7 :7                                                                                                   
Number-8 :8                                                                                                   
Number-9 :9                                                                                                   
Number-10 :10                                                                                                 
The sum of 10 no is : 55                                                                                      
The Average is : 5.500000

C Programming: Tips of the Day

Clearing a char array c

It depends on how you want to view the array. If you are viewing the array as a series of chars, then the only way to clear out the data is to touch every entry. memset is probably the most effective way to achieve this.

On the other hand, if you are choosing to view this as a C/C++ null terminated string, setting the first byte to 0 will effectively clear the string.
