C Program to Pass Command Line Arguments
C
// Program to demonstrate Command line arguments in C #include <stdio.h> #include <stdlib.h> int main(int argc, char* argv[]) { // code to calculate the sum of n numbers passed to CLA int i, sum = 0; // iterating the loop till the the number of // command-line arguments passed to the program // starting from index 1 for (i = 1; i < argc; i++) { sum = sum + atoi(argv[i]); } printf("Sum of %d numbers is : %d\n", argc - 1, sum); return 0; } |
Command Line Instruction
// assume that the file name is solution ./solution 10 20 30 40 50
Output
SUM of 5 numbers is: 150
Note: The command line arguments are separated by space so if you want to pass a space-separated string as a command line argument, then enclose them inside the “”.
