Solution

[1] Print every other character in the string “The quick brown fox jumps over the lazy old dog”

Solution :

#include <stdio.h>
#include <conio.h>

int main()
{
char str[] = \"The quick brown fox jumps over the lazy old dog\";
char flag = \'N\' ;
char cmp;
int i,j;
clrscr();

for( j = 65 ; j < 91 ; j++)
{
cmp =char(j);
flag = \'N\';
for( i = 0 ; i < str[i] !=\'\\0\' ; ++i)
{
   if(str[i] != cmp)
    {

    }

    else
    {
     flag = \'Y\';
     break;
    }

}

if(flag == \'N\')
{
   printf(\" %c \",cmp);
}

}

for( j = 97 ; j < 123 ; j++)
{
cmp =char(j);
flag = \'N\';
for( i = 0 ; i < str[i] !=\'\\0\' ; ++i)
{
   if(str[i] != cmp)
    {

    }

    else
    {
     flag = \'Y\';
     break;
    }

}

if(flag == \'N\')
{
   printf(\" %c \",cmp);
}

}

     getch();

    return 0;
}

[2] Print only the vowels in the string “The quick brown fox jumps over the lazy old dog”

#include <stdio.h>
#include <conio.h>
#include <string.h>

int main()
{
char str[] = \"The quick brown fox jumps over the lazy old dog\";
int i,length;
clrscr();

length = strlen(str);

for( i = 0 ; i < length ; i++)
{
   if(str[i] == \'a\' ||
      str[i] == \'e\' ||
   str[i] == \'i\' ||
   str[i] == \'o\' ||
   str[i] == \'u\' ||
   str[i] == \'A\' ||
   str[i] == \'E\' ||
   str[i] == \'I\' ||
   str[i] == \'O\' ||
   str[i] == \'U\'
        )
    {

    printf(\"%c\",str[i]);

           }
}   

     getch();

    return 0;
}

[3] Count the number of spaces in the string “The quick brown fox jumps over the lazy old dog”

#include <stdio.h>
#include <conio.h>

int main()
{
char *str,s[1000] = \"The quick brown fox jumps over the lazy old dog\";
int i,j, space;


clrscr();

str=s;
    for(space = 0;*str;str++)
       {
            if(*str!= \' \')
              continue;
         space++;
       }
    
printf(\"%d spaces\ \",space);
     getch();
    return 0;
}
