Question

Write a program which takes two integers as commandline

parameters and outputs the sum(c programming)

Answer 1

The question is about creating a C program that takes two integers from command line parameters and outputs their sum. Using argc and argv to handle parameters and atoi for conversion is crucial. The code includes error checking for argument count.

Step-by-step explanation:

The subject of this question is Computers and Technology, and it is at the College level. The student is asking for a C programming example that reads two integer values passed as command line parameters and calculates their sum. To complete this task, you would normally use the main function with command line parameters, int argc and char *argv[] which stands for argument count and argument vector respectively.

An example code snippet to achieve this would look like:

#include
#include

int main(int argc, char *argv[]) {
if (argc != 3) {
printf("Usage: %s ", argv[0]);
return 1;
}
int num1 = atoi(argv[1]);
int num2 = atoi(argv[2]);
int sum = num1 + num2;
printf("The sum is: %d\\", sum);

return 0;
}

Remember to compile the C program with a compiler such as gcc before trying to execute it with the correct number of parameters, otherwise it will provide usage information. This program will convert the command line arguments from strings to integers using the atoi function and then calculate and output the sum.
