What will be the output of the program (test.c) given below if it is executed from the command line?
cmd> test Amphisoft E-Box

#include<stdio.h>
int main(int argc, char **argv){
printf("%c", **++argv);
return 0;

Answer 1

Basically it is asking you, what will be the output if you pass arguments to your C program, test.c, from the command line.
The line which starts with cmd> is not part of the code. It is the line used in cmd for passing arguments to the main function of your program.
Here the arguments being passed are Amphisoft and E-box and test is the name of the c program. that's how you pass arguments from the command line.
