          C Program to check given String is Pangram or not

Pangram:

          A Pangram is a sentence containing every letter of the alphabet.

Example: Let us consider a sentence as given below:

The quick brown fox jumps over the lazy dog.

 The above sentence containing every letter of the alphabet.

Thus the Entered String is a Pangram String.

Now let us see the program code to check given String is Pangram or not and understand the code using the Explanation given below.

code:

#include<stdio.h>

#include<conio.h>

void main()

{

char s[100];

int i,used[26]={0},total=0;

clrscr();

printf("\n Enter the String:\n");

gets(s);

for(i=0;s[i]!='\0';i++)

{

if('a'<=s[i] && s[i]<='z')

{

total+=!used[s[i]-'a'];

used[s[i]-'a']=1;

}

else if('A'<=s[i] && s[i]<='Z')

{

total+=!used[s[i]-'A'];

used[s[i]-'A']=1;

}

}

if(total==26)

{

printf("\n The Entered String is a Pangram String.");

}

else

{

printf("\n The Entered String is not a Pangram String.");

}

getch();

}
