Using Pointers and Strings - C Programming

Write a C program to count number of words.

/* C Program to count number of words */

#include <stdio.h>

main()

{

char str[100], *ps;

int nword = 0;

printf ("\n Enter a string");

ps=str;

gets(ps);

while (*ps==32 && *ps!=Null)

ps++;

if (*ps!=null)

nword++;

for (ps=str; *ps!=NULL; ps++)

{

if (*ps!=32 && *(ps‒1)==32)

nword++;

}

printf("%d word(s) in the given string", nword);

}

OUTPUT

Enter a string

I am a student.

4 word(s) in the given string.

EXPLANATION: In the above program str[] declared as a character type array. Variable ps declared as pointer variable. Read the string ps from the terminal. The while loop checks the condition *ps=32 && *ps!=Null if condition satisfies then increment the variable ps by 1. if statement checks the conditions *ps!=Null and executes the block of statement then prints the string nword.
