delete an element at any position of the array



If you delete any element of the array you can write this code. You will start [position-1] and visit [size-1].
After visiting all elements, you have to decreases the [size--].

 

for(i=position-1; i<size-1; i++) {
array[i] = array[i+1];
}
size--

#include<stdio.h>
#define MAX_SIZE 10
int main() {

int array[MAX_SIZE],size,i,position,Length =0;

/* Input size of the array */
printf("Enter the size of the array:\n");
scanf("%d",&size);


/* if MAX_SIZE < new size then overflow condition!*/
Length = sizeof(array)/sizeof(array[0]);

if(Length < size) {
printf("overflow condition! Please enter size between 1 to %d", Length);
} else {

/* Input elements in array */
printf("Enter %d elements:\n",size);

for(i=0; i<size; i++) {
scanf("%d",&array[i]);
}

/* Input position to delete */
printf("Enter the deleting position:\n");
scanf("%d",&position);

/* If position of element is not valid */
if(position>size ||position <=0) {
printf("Please enter position between 1 to %d", size);
return;
} else {
/* start form position-1 */
for(i=position-1; i<size-1; i++) {
array[i] = array[i+1];
}
size--;

/* Print array after insert */
printf("Array elements after deleting:\n");
for(i=0; i<size; i++) {
printf("%d ",array[i]);
}
}

}

return 0;
}



Output

Enter the size of the array:
8
Enter 8 elements:
10 20 30 40 50 60 70 80
Enter the deleting position:
3
Array elements after deleting:
10 20 40 50 60 70 80
