C Exercises: Pictorial: Print all the alphabets.

Sample Solution:

C Code:

#include <stdio.h>

int main()
{
    char alph[27];
    int x;
    char *ptr;
 	printf("\n\n Pointer : Print all the alphabets:\n"); 
	printf("----------------------------------------\n");
    ptr = alph;     

    for(x=0;x<26;x++)
    {
        *ptr=x+'A';
        ptr++;
    }
    ptr = alph;

printf(" The Alphabets are : \n");
    for(x=0;x<26;x++)
    {
       printf(" %c ", *ptr);
        ptr++;
    }
    printf("\n\n");
    return(0);
}

Sample Output:

 Pointer : Print all the alphabates:                                                                          
----------------------------------------                                                                      
 The Alphabates are :                                                                                         
 A  B  C  D  E  F  G  H  I  J  K  L  M  N  O  P  Q  R  S  T  U  V  W  X  Y  Z

C Programming: Tips of the Day

Static variable inside of a function in C

The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().

The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.

The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
