// Program to delete an element at specific position in an array #include<stdio.h> #include<stdlib.h> int main() { int a[50],i,size,position,value; printf("Enter the size of the array:"); scanf("%d",&size); if(size>50) { printf("Invalid size input"); exit(1); } printf("Enter the array elements:"); for(i=0 ; i<size ; i++) scanf("%d",&a[i]); printf("Enter at which position you want to delete the element:"); scanf("%d",&position); if(position<=0 || position >size) { printf("Invalid position entered"); exit(1); } value=a[position-1]; for(i=position-1 ; i< size-1 ; i++) { a[i]=a[i+1]; } size--; printf("The deleted element is %d\n",value); printf("Resultant array after deletion:\n"); for(i=0 ; i< size ;i++) printf("%d\t",a[i]); return 0; }

Deletion: Deletion is an operation or process that involves removing or eliminating a specific element of an array

//Program to insert an element at specific position in a unsorted array. #include<stdio.h> #include<stdlib.h> int main() { int a[50],i,size,position,val; printf("Enter the size of the array :"); scanf("%d",&size); if(size > 50) //bound checking { printf("Invalid size input"); exit(1); } printf("Enter elements into the array:"); for(i=0; i< size ; i++) scanf("%d",&a[i]); printf("Enter at which position you want insert element:"); scanf("%d",&position); printf("Enter the value to be inserted:"); scanf("%d",&val); a[size]=a[position-1]; size++; a[position-1]=val; printf("Resultant array after insertion:\n"); for(i=0 ; i<size ; i++) printf("%d\t",a[i]); return 0; }
