In the following example, we will find the average of numbers between 1 and 10 using for loop.
Example
C Compiler
#include<stdio.h>int main() {
int start =1;
int end =10;
int total =0;
float count = (end - start) +1;
float average =0;
printf("Average of numbers between %d and %d:\n", start, end);
for(start=start; start<=end; start++)
total += start;
printf("\nTotal = %d", total);
printf("\ncount = %.f", count);
average = total / count;
printf("\nAverage is %.1f", average);
return0;
}
Output
Average of numbers between 1 and 10:
Total = 55
count = 10
Average is 5.5
Using while loop
In the following example, we will find the average of numbers between 1 and 10 using while loop.
Example
C Compiler
#include<stdio.h>int main() {
int start =1;
int end =10;
int total =0;
float count = (end - start) +1;
float average =0;
printf("Average of numbers between %d and %d:\n", start, end);
while(start <= end)
{
total += start;
start++;
}
printf("\nTotal = %d", total);
printf("\ncount = %.f", count);
average = total / count;
printf("\nAverage is %.1f", average);
return0;
}
Output
Average of numbers between 1 and 10:
Total = 55
count = 10
Average is 5.5
Using do while loop
In the following example, we will find the average of numbers between 1 and 10 using do while loop.
Example
C Compiler
#include<stdio.h>int main() {
int start =1;
int end =10;
int total =0;
float count = (end - start) +1;
float average =0;
printf("Average of numbers between %d and %d:\n", start, end);
do{
total += start;
start++;
}while(start <= end);
printf("\nTotal = %d", total);
printf("\ncount = %.f", count);
average = total / count;
printf("\nAverage is %.1f", average);
return0;
}
Output
Average of numbers between 1 and 10:
Total = 55
count = 10
Average is 5.5
Find Average of N Numbers for any Given Range
In the following example, we will find the average of N numbers between the user given range.
Example
C Compiler
#include<stdio.h>int main() {
int start, end;
int total =0;
float count =0;
float average =0;
printf("Enter a (int) starting number: ");
scanf("%d", &start);
printf("Enter an (int) ending number: ");
scanf("%d", &end);
count = (end - start) +1;
printf("Average of numbers between %d and %d:\n", start, end);
for(start=start; start<=end; start++)
total += start;
printf("\nTotal = %d", total);
printf("\ncount = %.f", count);
average = total / count;
printf("\nAverage is %.1f", average);
return0;
}
Output
Enter a (int) starting number: 5
Enter an (int) ending number: 14
Average of numbers between 5 and 14:
Total = 95
count = 10
Average is 9.5
