Array

---

In C, an array is a collection of elements of the same type stored in contiguous memory locations. Arrays in C are useful for storing multiple values of the same type, and you can access each value using an index.

Project 1

#include <stdio.h>
int main()
{
    int num[5], total = 0;
    int i;
    for (i = 0; i < 5; i++)
    {
        printf("Enter number : ");
        scanf("%d", &num[i]);
        total += num[i];
    }
    printf("\nAverage = % .2f\n", total / 5.0);
}

Output :

Enter number : 10
Enter number : 20
Enter number : 30
Enter number : 40
Enter number : 50

Average =  30.00

Project 2

#include <stdio.h>

int main()
{
    int num[5], min;
    int i;
    for (i = 0; i < 5; i++)
    {
        printf("Enter number : ");
        scanf("%d", &num[i]);
    }
    min = num[0];
    for (i = 0; i < 5; i++){
        if (min > num[i])
        {
            min = num[i];
        }
    }
        printf("\nMinimum Number : %d\n", min);
}

Output :

Enter number : 1
Enter number : 10
Enter number : 100
Enter number : 1000
Enter number : 10000

Minimum Number : 1

Project 3

#include <stdio.h>

int main()
{
    int num[10];
    int i,j = 0;
    for (i = 0; i < 10; i++)
    {
        printf("Enter number : ");
        scanf("%d", &num[i]);
    }
    for (i = 0; i < 10; i++){
        if (num[i] % 2 == 0)
        {
            printf("%d\t",num[i]);
            j++;
        }
    }
        printf("\nNumber of Even : %d\n", j);
}

Output :

Enter number : 3
Enter number : 4
Enter number : 5
Enter number : 6
Enter number : 7
Enter number : 8
Enter number : 9
Enter number : 10
2       4       6       8       10
Number of Even : 5

Project 4

#include <stdio.h>
#include <string.h>

int main() {
    char input[10];
    printf("Enter String : ");
    scanf("%s", input);

    int length = strlen(input);
    printf("Length of the string: %d\n", length);
    
    return 0;
}

Output :

Enter String : Hello
Length of the string: 5
