int main(int argc, char* argv[])
{
int first, second, total;
if (argc < 2)//checking if there are enough arguments
{
printf("not enough values\n");
return -1;//terminate program
}
total = 0;
for (int i = 1; i < argc; i++)
{
//atoi convert a string into int. doing this to use operator
total = total + atoi(argv[i]);//add current total to next argumment
}
printf("final total sum: %d\n", total);//printing final total
return 0;
}
Explanation:
For command line arguments you have to use command prompt. It varies depending on you machine and where you code is placed.
So, go to command line, called "command prompt" on Windows. This should open the black screen, also called the Terminal. A picture is attached in the answer. Then you have to NAVIGATE to the directory of your program. So, let's say your code is on your desktop. You will have to navigate to your desktop. To do this, type:
"cd Desktop", and press enter.
The picture of my process is attached below too.
Then, the program we have made is called addnumbers. we will type,
"addnumbers 10 20 30 40 50"
add numbers is the name of the program followed by arguments, separated with spaces.
