C Program : C Program to Add two numbers using Command Line Arguments

#include<stdio.h>
void main(int argc, char * argv[]) {
   int i, sum = 0;
   if (argc != 3) {
      printf("You have forgot to type numbers.");
      exit(1);
   }
   printf("The sum is : ");
   for (i = 1; i < argc; i++)
      sum = sum + atoi(argv[i]);
   printf("%d", sum);
}

#include<stdio.h>

void main(int argc, char * argv[]) {

int i, sum = 0;

if (argc != 3) {

printf("You have forgot to type numbers.");

exit(1);

}

printf("The sum is : ");

for (i = 1; i < argc; i++)

sum = sum + atoi(argv[i]);

printf("%d", sum);

}

Output :

The sum is : 30

1	The sum is : 30

Steps to be followed to execute program using Command Line Argument inside Borland C/C++ Compiler :

Step 1 : Write a Program
Step 2 : Open Command Prompt inside Borland C/C++.
Step 3 : Click on DOS Shell.

Step 4 : Inside Command Prompt type this command.

C:TCBIN>add 10 20

1	C:TCBIN>add 10 20

Step 5 : Hit Enter , You will get following Output.

C:TCBIN>add 10 20
The sum is : 30
C:TCBIN>

C:TCBIN>add 10 20

The sum is : 30

C:TCBIN>

Step 6 : Type “exit” command to return to Turbo C/C++ Screen
