Answer 1

Pangrams are words or sentences containing every letter of the alphabet at least once; the best known English example being A quick brown fox jumps over the lazy dog .

#include <stdio.h>

 int main(void)
 {
    int index, i, pangram;
    char ch, x[26] = {0};
    printf("\n\n------------------------------------------\n");
    printf("Enter a sentence to check if is a pangram\n");
    printf("------------------------------------------\n");
    printf("----------- Pangram Program --------------\n");
    printf("Enter a pangram: ");
 /* This While Loop checking if is a pangram or not. The program increment 1 for each that letter
 you enter. So, if you have at least one and each letter is a pangram*/
    while ((ch = getchar()) != '\n'){   // This time I dont used scanf, I used getchar
        if('A'<=ch&&ch<='Z')// checking if Cap letter
            index = ch-'A';
        else if('a'<=ch&&ch<='z') // checking if isn't Cap letter
            index = ch-'a';
        else
            continue;

    x[index] = 1;//  Here is stored all the letter with numbers.
    }

    pangram = 1;
// Basically this is loop that check if you have all letters.
    for (i = 0; i < 26; ++i) {
        if (x[i] == 0)
            pangram = 0;
    }
// If you have all letter, the array  increment 1 and is a pangram
    if (pangram == 1){
        printf("------------------------------------------\n");
        printf("Your sentence have all letter so is, Pangram\n");
        printf("------------------------------------------\n");
        printf("  By: <span class="wp-smiley wp-emoji wp-emoji-lol" title="XD">XD</span> Creations");
}
// If you dont have all letter, the array dont increment  and isn't a pangram
    else if(pangram == 0) {
        printf("------------------------------------------\n");
        printf("This sentence is not a  Pangram\n");
        printf("------------------------------------------\n");
        printf(" By: <span class="wp-smiley wp-emoji wp-emoji-lol" title="XD">XD</span> Creations\n");
    }
 printf("\n\n");
    system("PAUSE");// system("PAUSE"); is just for windows
    return 0;
}
