Write a program to insert/delete in linear array at specific position.
#include <stdio.h> int main () { int arr [ 100 ] ; int i, item, pos, size=7; printf ( "Enter 7 elements: " ) ; // reading array for ( i = 0; i < size; i++ ) scanf ( "%d" ,&arr [ i ]) ; // print the original array printf ( "Array before insertion: " ) ; for ( i = 0; i < size; i++ ) printf ( "%d " , arr [ i ]) ; printf ( "\n" ) ; // read element to be inserted printf ( "Enter the element to be inserted: " ) ; scanf ( "%d" ,&item ) ; // read position at which element is to be inserted printf ( "Enter the position at which the element is to be inserted: " ) ; scanf ( "%d" ,&pos ) ; // increase the size size++; // shift elements forward for ( i = size-1; i > = pos; i-- ) arr [ i ] = arr [ i - 1 ] ; // insert item at position arr [ pos - 1 ] = i...
