    97 -> a, 98 -> b, ..., 122 -> z

    Hi,

    I study C language. As an exercise I decided to write a program, that writes all 26 letters of english alphabet on one line.

    I know that in ASCII:
    a...97
    b...98
    ........
    z...122

    I know how to make it using for loop, but I don't know how to convert 97 in dec to a character. I was looking for some functions (I have found atoi(), sscanf(), sprintf()) but I wasn't able to finish it. Could you please help me?

    Code:
    main()
    
    {
          
    int i;
    char s[1];
    
    for(i=97;i<123;i=i+1){
                      s=atoi(i);          /* I think here is the problem part */
                      printf("%c",s);
    
                      
                      }
          
    getch();      
    }
    Thank you.

    You're going to smack yourself on the forehead when I tell you.

    Ready?

    Just
    Code:
    printf("%c", theNumber Or Variable Holding the number Goes Here);
    OK, go smack yourself!

    Code:
    for ( i = 'a' ; i <= 'z' ; i = i + 1 )
    Also works on the ASCII character set.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Code:
    s=atoi(i);
    atoi is a function which converts string to an integer. This would work in your case. What you just have to do is to print integer as char in the printf statement. As Adak shown. Between getch is a non-standard function. Use getchar instead and also main should return a value int.
