Make a program will read 3 numbers from the user and tell the largest number. Make the following 4 functions in addition to the main.

showProgInfo This function will show the program information shown below.

*****************************************************

This program will ask you to enter 3 numbers and find the largest.

*****************************************************

getNum This function asks the user to enter one number and returns it. Call this function 3 times in the main to get 3 numbers from the user.

findLargest This function finds the largest value among the 3 numbers and returns it.

This is what I have, please I need help

#include

using namespace std;

void showProgInfo();

int getNum(int num1, int num2, int num3);

int largerst(int num1, int num2,int num3);

void printResult(int s,int num1, int num2, int num3);

int main()

{

int num1;

int num2;

int num3;

int largerst;

showProgInfo ();

getNum(num1,num2,num3);

findLargest(num1,num2,num3);

printResult(largets,num1, num2,num3);

return 0;

}

int showProgInfo()

{

cout<<"********************************************************************"<

cout<<" This program will ask you to enter 3 numbers and find the largest. "<

cout<<"********************************************************************"<

}

int getNum(int num1, int num2, int num3)

{

cout<<"Enter a number: ";

cin>>num1>>endl;

cout<<"Enter a number: ";

cin>>num2>>endl;

cout<<"Enter a number: ";

cin>>num3>>endl;

return showProgInfo;

}

int findLargest(int num1, int num2,int num3)

{

int largest=0;

if( num1>num2)

largest=num2;

else

largest= num1;

if(num1

largest=num3;

return largerst;

}

void printResult(int largets,int num1, int num2, int num3)

{

cout<<"The largest number among "<< num1<<", "<

}
