In this program, we will discuss a simple concept of program to find the largest number among three numbers in the Cpp programming language.
In this topic, we learn how to find the biggest number from given three numbers. we can use the operator in C++ language to find the biggest number of this program.
Using if statements to find the largest number
Among integer numbers
Program 1:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 |
#include <iostream> #include <conio.h> using namespace std; int main() { int num1, num2,num3; //declare the variables cout<<"Enter the first number to compare: "; cin>>num1;//get input from user for num1 cout<<"Enter the second number to compare: "; cin>>num2;//get input from user for num2 cout<<"Enter the third number to compare: "; cin>>num3;//get input from user for num3 if(num1>=num2 && num1>=num3){ cout<<"\nLargest number is:"<<num1; }//num1 compare num 2 and num 3 if(num2>=num1 && num2>=num3){ cout<<"\nLargest number is:"<<num2; }//num2 compare num1 and num3 if(num3>=num1 && num3>=num2){ cout<<"\nLargest number is:"<<num3; }//num3 compare num1 and num2 getch(); return 0; } |
When the above code is compiled and executed, it produces the following results
|
1 2 3 4 5 6 |
Enter the first number to compare: 45 Enter the second number to compare: 87 Enter the third number to compare: 34 Largest number is: 87 |
Among floating point numbers

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 |
#include <iostream> #include <conio.h> using namespace std; int main() { double num1, num2,num3; //declare the variables cout<<"Enter the first number to compare: "; cin>>num1;//get input from user for num1 cout<<"Enter the second number to compare: "; cin>>num2;//get input from user for num2 cout<<"Enter the third number to compare: "; cin>>num3;//get input from user for num3 if(num1>=num2 && num1>=num3){ cout<<"\nLargest number is:"<<num1; }//num1 compare num 2 and num 3 if(num2>=num1 && num2>=num3){ cout<<"\nLargest number is:"<<num2; }//num2 compare num1 and num3 if(num3>=num1 && num3>=num2){ cout<<"\nLargest number is:"<<num3; }//num3 compare num1 and num2 getch(); return 0; } |
Using if -else statements to find the largest number
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 |
#include <iostream> #include <conio.h> using namespace std; int main() { int num1,num2,num3; //declare the variables cout<<"Enter the first number to compare: "; cin>>num1;//get input from user for num1 cout<<"Enter the second number to compare: "; cin>>num2;//get input from user for num2 cout<<"Enter the third number to compare: "; cin>>num3;//get input from user for num3 if(num1>=num2 && num1>=num3){ cout<<"\nLargest number is: "<<num1; }//num1 compare num 2 and num 3 else if(num2>=num1 && num2>=num3){ cout<<"\nLargest number is: "<<num2; }//num2 compare num1 and num3 else{ cout<<"\nLargest number is: "<<num2; } getch(); return 0; } |
