C Program to Find the Largest/Longest String

Write a c program to accept n strings and print the string with maximum length i.e write a c program to find the largest/longest string.

Algorithm / Solution:

Here is the solution for C program to find the largest or longest string.

1. Start
2. Use 2d string to store n arrays.
3. Use for loop to loop through strings.
4. Use strlen() function to check length of each string.
5. Assign length of string with index 0 to Max.
6. Compare Max with length of n'th string.
7. Each time store index of corresponding string when Max changes.
8. Display string with Max length.
9. Stop.

C Program / Source Code :

Here is the source code of C program to find the largest or longest string.

/*Aim: Write a program to find the largest or longest string.*/
#include<stdio.h>
#include<string.h>
#define size 100 
#define wsize 20
void Longest_Word(char str[][20],int n); // Longest_Word Function Prototype
void main()
{
	char str[size][wsize];
	int i,count=0,n;
	printf("\n How many words to accept:- ");
	scanf("%d",&n);
	printf("\n Enter %d words:- \n \n",n);
	for(i=0;i<n;i++)
	scanf("%s",str[i]);
	Longest_Word(str,n);
}
// Longest_Word Function
void Longest_Word(char str[][20],int n)
{
	int i,Max,len1,c;
	Max=strlen(str[0]);
	for(i=1;i<n;i++)
	{
	len1=strlen(str[i]);
	if(len1>Max)
	{
		c=i;
		Max=len1;
	}
}
	printf("\n The longest string among all is \"%s\" \n \n",str[c]);
}
/* Output of above code:-
 How many words to accept:- 5
 Enter 5 words:- 
 
Halo
I  
Am       
Master      
Chief

 The longest string among all is "Master"
