# Program to find largest number among n numbers

0 Suresh Chand June 2, 2021

In this example, We will learn a program to find largest number among n numbers. You must have knowledge in the following topics before looking at this example

## Algorithm

This is the algorithm of this program

```Step 1: Start
Step 2: Initialize 2 integer variables n and i, and two float variables c and largest
Step 3: Take input from user and store in n
Step 4: Take input from user and store in largest
Step 5: Assign i = 2
Step 6: REPEAT this step until i <= n
Take input from user and store in c
IF largest < c
largest = c
Increase i by 1
Step 7: Print largest
Step 8: End```

## Flowchart

This is the flowchart of this program

## CODE: Program to find largest number

Now, We will see the code to find largest number among n numbers

``````#include <stdio.h>

int main()
{
int n, i;
float c, largest;

printf("How many numbers : ");
scanf("%d", &n);

printf("\nEnter %d numbers :\n", n);

printf("\n\tElement 1: ");

//Here is the important step
// Initialize largest variable with first element
scanf("%f", &largest);

for (i = 2; i <= n; i++)
{
printf("\n\tElement %d  : ", i);
scanf("%f", &c);

/*
if input number is larger than the
current largest number
*/
if (largest < c)
largest = c; // update big to the larger value
}

printf("\nThe largest of the %d numbers is  %f ", n, largest);
return 0;
}``````

The output of above program is

``````How many numbers : 4

Enter 4 numbers :

Element 1: 1

Element 2  : 4

Element 3  : 7

Element 4  : 3

The largest of the 4 numbers is  7.000000``````
