Write C programme Counting the number of words in a given string and Concatenating two given strings

Write C programme for followings:

            i)  Counting the number of words in a given string 

i)                     #include<stdio.h>

#include<conio.h>

void main()

{

        clrscr();

        char str[1000];

        int i=0;

        printf(“Enter the string: “);

        scanf(“%s”,str);

        while(str[i]!=’\0’)

        {

                        i++;

        }

        printf(“There are %d words.”i);

        getchar();

        getch();

}

            ii) Concatenating two given strings

             #include<stdio.h>

#include<conio.h>

void main()

{

        clrscr();

        char a[1000],b[1000];

        int i=0,j=0,k;

        printf(“Enter the string: “);

        scanf(“%s”,a);

        printf(“Enter the string: “);

        scanf(“%s”,b);

        while(a[i]!=’\0’)

        {

                        i++;

        }

        while(b[j]!=’\0’)

        {

                        j++;

        }

        for(k=0;k<j;k++)

        {

                        a[i+k]=b[k];

        }

        printf(“%s”,a);

        getchar();

        getch();

}
