This program produces the error "Illegal structure operation". {geshibot language="c"}#include #include const int i=10; void main() { const int i=20; clrscr(); cout

cprintf is defined to send formatted output to the text window on the screen. And printf directs its output to the stdout. What is the difference between stdout and a text window then? Does the screen serve differently while using cprintf and printf? Please explain

What is the difference between cprintf and printf? Please explain in detail.

I think the original question was not a typo. The original question was printf, not fprintf, compared to cprintf. And I think printf output goes to stdout (standard out) which by default goes to con (the console). cprintf output goes only to con.

Cprintf outputs to the console device.
fprintf outputs to a stream specified by the 1st parameter.

I=5;
++i * ++i; (6*7)(if the i is the value 7)
7*7;
49

The ans is 49 only
bcoz i cant be 2 values(6, 7) at a time so, i should be 7 at last
thats why 7*7 = 49.

When we press enter to end the program and press Alt+F5 to see the output again, we see that the getche() function places the cursor at the beginning of the line. So, does the enter key specify carriage return in this case. But while entering output, it works as a newline character... Please explain the difference in both the contexts.

Enter key is line feed.

Can you please explain the declaration of getch() function that is "int getch(void)"? I have the doubt that if its return type is int, why is the character typed from the keyboard is displayed as it is? It should be displayed in its ASCII value. Also, what does void as parameter in this function stand for???

In C, all the character-oriented functions (getc, fgetc, getchar, etc.) return int instead of char, mainly to support an out-of-band value for EOF (an integer expression with a negative value).

The "void" in the parameter list indicates that the function takes no parameters.
