Answer 1

Answer:

In this example, you will learn to calculate the average of n number of elements entered by the user using arrays.

To understand this example, you should have the knowledge of the following C programming topics:

C while and do...while Loop

C for Loop

C Arrays

Store Numbers and Calculate Average Using Arrays

#include <stdio.h>

int main() {

int n, i;

float num[100], sum = 0.0, avg;

printf("Enter the numbers of elements: ");

scanf("%d", &n);

while (n > 100 || n < 1) {

printf("Error! number should in range of (1 to 100).\n");

printf("Enter the number again: ");

scanf("%d", &n);

}

for (i = 0; i < n; ++i) {

printf("%d. Enter number: ", i + 1);

scanf("%f", &num[i]);

sum += num[i];

}

avg = sum / n;

printf("Average = %.2f", avg);

return 0;

}

Output

Enter the numbers of elements: 6

1. Enter number: 45.3

2. Enter number: 67.5

3. Enter number: -45.6

4. Enter number: 20.34

5. Enter number: 33

6. Enter number: 45.6

Average = 27.69

$\color{grey}{\sf \#python \: }$

$\sf Number \_one=int(input("First \: Number"))$

$\sf Number \_two=int(input("Second \: Number"))$

$\sf Average=int((Number \_one+Number \_two)/2)$

$\sf print(Average)$

$\sf{ \purple{in \: our \: case : }}$

$\sf{numbers \:are \: 30 \: and \: 50}$

$\orange{ \therefore \sf{output \: will \: be \: 40}}$
