Question

Must be C++ 11

Write a function named insertinArray that takes the following parameters: list: an integer array index: index at which to insert the new item numitems: number of items currently in the array arrayCapacity: capacity of the array newVal: value to insert into the array If the array is at capacity then the function should return-1. Otherwise, insert newVal at index and return O for success int insertInArray(int listl 1, int index, int numItems, int arrayCapacity, int newVal) For example, if the array is (9, 2, 8, 3) and it has the capacity to add a new value of 5 at index 2, then the resulting array should be (9, 2, 5, 8, 3) and the function should return O. The numitems variable will increment from 4 to 5

ANSWER: Here I am giving you the code and output if you have any problem then you can comment or like my solution.

CODE:

#include <iostream>

using namespace std;

int insertInArray(int list[],int index, int *numItems,int arrayCapacity, int newVal)

{

if(index>arrayCapacity)

return -1;

else

{

for(int i=arrayCapacity; i>index; i--)

{

list[i]=list[i-1];

}

list[index]=newVal;

return 0;

}

}

int main()

{

int list[4]={9,8,3};

int index, newVal;

cout<<"Enter an index to insert element :";

cin>>index;

int numItems=0;

for(int i=0;i<4;i++)

{

if(list[i]!=NULL)

numItems++;

}

int arrayCapacity=4;

cout<<"Enter your value to insert :";

cin>>newVal;

cout<<"\nArray before Inserting the new value.";

for(int i=0;i<4;i++)

{

if(list[i]!=NULL)

cout<<list[i]<<" ";

}

int rs=insertInArray(list,index,&numItems,arrayCapacity,newVal);

if(rs<0)

cout<<"You can not insert the value array is full or wrong index you entered.";

else{

cout<<"\nArray after Inserting the new value.";

for(int i=0;i<4;i++)

cout<<list[i]<<" ";

}

}

OUTPUT:
