Add numbers using command line arguments (CLA)

#include<stdio.h>
#include<conio.h>
#include<stdlib.h>

void main(int argc,char *argv[])
{
int sum=0,i;//Compare if proper number of arguments have been entered
if(argc<3)
{
printf("Insufficient number of arguments:\n");
getch();
return 0;
}

//Add all the numbers entered using atoi function
for(i=1;i<argc;i++)
{
sum+=atoi(argv[i]);
}

//print the sum
printf("Ans=%d",sum);
getch();
}

A simple example showing some comparison operators

#include
int main()
{
int number1 , number2;
printf("Enter the number1 number to compare.\n");
scanf("%d",&number1);
printf("Enter the number2 number to compare.\n");
scanf("%d",&number2);
printf("number1 > number2 has the value %d\n", number1 > number2);
printf("number1 < number2 has the value %d\n", number1 < number2);
printf("number1 == number2 has the value %d\n", number1 == number2);
return 0;
}
