Answer 1

[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\n",space);
     getch();
    return 0;
}
