c programs using Array

 1.write a c program to ftnd the average of 10 random numbers

#include <stdio.h>

main()

 {

    int n, t;

    float num[100], sum = 0, avg;

 

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

    scanf("%d", &n);

 

   

        printf("Enter the number: ");

        scanf("%d", &n);

    }

 

    for (t = 0; t < n; t++)

 {

        printf("Enter number: ");

        scanf("%f", &num[t]);

        sum += num[t];

    }

 

    avg = sum / n;

    printf("Average = %f", avg);

}

Outtut

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

 

2.write a c Program to find the Largest number from a random 10 numbers

#include <stdio.h>

 main()

{

    int t, n;

    float a[100];

    printf("Enter any number: ");

    scanf("%d", &n);

 

    for (t = 0; t < n; ++t)

 {

        printf("Enter number");

        scanf("%f", &a[t]);

    }

 

    // storing the largest number to a[0]

    for (t = 1; t < n; t++)

{

        for (a[0] < a[t])

            a[0] = a[t];

    }

 

    printf("Largest element = %f", a[0]);

}

Outtut

Enter the number : 5

Enter number1: 34.5

Enter number2: 2.4

Enter number3: -35.5

Enter number4: 38.7

Enter number5: 24.5

Largest element = 38.70
