Counting program in C

Counting is sequence of whole numbers in ascending order without zero. Developing a program of counting in C programming language is easy and we shall see here in this chapter.

Algorithm

Let's first see what should be the step-by-step procedure for counting −

START
   Step 1 → Define start and end of counting
   Step 2 → Iterate from start to end
   Step 3 → Display loop value at each iteration
STOP

Pseudocode

Let's now see the pseudocode of this algorithm −

procedure counting()

   FOR value = START to END DO
      DISPLAY value
   END FOR

end procedure

Implementation

Now, we shall see the actual implementation of the program −

#include <stdio.h>

int main() {
   int i, start, end;

   start = 1;
   end = 10;

   for(i = start; i <= end; i++) 
      printf("%2d\n", i);

   return 0;
}

Output

Output of this program should be −

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
