Question

Write a complete C++ program to ask the user to enter 4 integers. The program must use a function to find the largest integer among them and print it on the screen. Typical output screen should be as following:

Note: the code must contain function to find the largest number.

Enter four integers 1 2 4 0 Largest integer is 4 03 (35 points)

Answer 1

#include<iostream>

#include<string>

#include<sstream>

using namespace std;

int largestNumber(int b[],int size){

int c;

c=b[0];

for(int i=0;i<size;i++){

if(b[i]>c)

c=b[i];

}

return c;

}

int main() {

  

cout<<"Enter four integers seperated by comma ',': ";

string my_str;

int a[4],j=0;

cin>>my_str;

const char d=',';

std::stringstream ss(my_str);

std::string s;

while (std::getline(ss, s, d)) {

a[j]=stoi(s);

j++;

}

cout<<"Largest Integer is: "<<largestNumber(a,4);

}

Output:

5 input CO Enter four integers seperated by mma ': 4,5,3,2 Largest Integer is: 5

If output required as per given in question with input entry with spaces, then use below code.

#include<iostream>

#include<string>

#include<sstream>

using namespace std;

int largestNumber(int b[],int size){

int c;

c=b[0];

for(int i=0;i<size;i++){

if(b[i]>c)

c=b[i];

}

return c;

}

int main() {

  

cout<<"Enter four integers ";

string my_str;

int a[4],j=0;

getline(cin,my_str);

const char d=' ';

std::stringstream ss(my_str);

std::string s;

while (std::getline(ss, s, d)) {

a[j]=stoi(s);

j++;

}

cout<<"Largest Integer is "<<largestNumber(a,4);

}

Output:

input Enter four integers 1 4 3 2 Largest Integer is 4
