C programs on searching word - character from character array

String is very useful chapter in C programming language. In previous several posts I have discussed on this chapter. Here are another two C programs on array – char type.

program to count line,word,character from a string.

 #include < stdio.h >

#include< conio.h >

void main()

{

   char ch;

   int blank=1,character=0,line=1;

   clrscr();

   printf("Enter the string with blanks,tabs and new line\n");

   printf("At the end put a full stop.\n");

   while(ch!='.')

   {

   /* read a character from the standard input stream */

   ch = getc(stdin);

   if(ch==' ')

   blank++;

   else if(ch=='\n')

   line++;

   else if(ch!='.')

   character++;

   }

   printf("\nWord %d\nCharacters %d\nLine %d",blank,character,line);

   getch();

}

 Write a program that converts characters like newline, blank and tab into visible sequence like \n, \b and \t. 

#include < stdio.h>

#include< conio.h>

#include< string.h>

void main()

{

   char str1[100],str2[100];

   int i=0,j=0;

   clrscr();

   printf("Enter the string with blanks,tabs and new line\n");

   printf("At the end put full stop.\n");

   gets(str1);

   while(str1[i]!='.')

   {

    switch(str1[i])

   {

   case ' ':

              {

              str2[j]=';';

              j++;

              str2[j]='b';

              j++;

              i++;

                break;

             }

  case '\t':

              {

               str2[j]=';';

              j++;

              str2[j]='t';

              j++;

              i++;

                break;

              }

  case '\n':

              {

              str2[j]=';';

              j++;

              str2[j]='n';

              j++;

              i++;

                break;

              }

  default :

             {

             str2[j]=str1[i];

             j++;

             i++;

              break;

             }

   }

 }

 str2[j]='\0';

 for(i=0;i<strlen(str2);i++)

 {

 if(str2[i]==';')

 printf("\\");

 else

 printf("%c",str2[i]);

 }

   getch();

}
