Question:22
C program to insert an element in the array?
Sol:

#include<stdio.h>

int main()
{
   int a[50],n,i,n1,pos,b;
//clrscr();
printf("Enter total elements ");
scanf("%d",&n);
for(i=0;i<n;i++)
{
printf("Enter the element ");
scanf("%d",&a[i]);
}

printf("Enter the position ");
scanf("%d",&pos);
printf("Enter the value to insert ");
scanf("%d",&n1);

pos=pos-1;
b=n;
while(b>=pos)
{
a[b]=a[b-1];
b--;
}
a[pos]=n1;
n++; //
for(i=0;i<n;i++)
{
printf("%d\n",a[i]);
}
    return 0;
}

/* Output */
Enter total elements 5
Enter the element 10
Enter the element 20
Enter the element 30
Enter the element 40
Enter the element 50
Enter the position 3
Enter the value to insert 500

Question:23
C program to delete an element from the array?
Sol:

#include<stdio.h>

int main()
{
    int a[50],n,i,n1,pos,b;
    /* clrscr(); */

    printf("Enter total elements ");
    scanf("%d",&n);
    for(i=0;i<n;i++)
    {
        printf("Enter the element ");
        scanf("%d",&a[i]);
    }
    printf("Enter the position ");
    scanf("%d",&pos);
    pos=pos-1;
    b=pos;
    while(b<=n)
    {
        a[b]=a[b+1];
        b++;
    }
    n--;//
    for(i=0;i<n;i++)
    {
        printf("%d\n",a[i]);
    }
    return 0;
}

/* Output */
Enter total elements 5
Enter the element 10
Enter the element 20
Enter the element 30
Enter the element 40
Enter the element 50
Enter the position 3
