Q8) Write a program in C++ to input a sentence and print the longest word.
Program
#include <iostream>
#include <conio.h>
#include <string.h>
#include <stdio.h>
using namespace std;
int main()
{
char s[100],w[50],lw[50];
int i,p;
cout<<"Enter a sentence\n";
gets(s);
for(i=0; i<strlen(s); i++)
{
if(s[i]!=' ')
{
// store the characters in array w until we find a space
w[p]=s[i];
p++;
}
else
{
// terminate the word by a null character
w[p]='\0';
// check if word length is greater than longest word (lw)
if(strlen(w)>strlen(lw))
{
strcpy(lw,w);
}
p=0;
}
}
cout<<"Longest word = "<<lw;
return 0;
}Output
Enter a sentence I am learning to code in C++ Longest word = learning
