Answer:computer8
First it will print computer and printf() is a predefined function it will return how many characters printed In this case it is printing 8 characters it will return 8.

OutPut :computer8

answer is computer8 as printf will return the number charcters enclosed within it's function parentheses and one clue is the format specifier %d that is usually used with numbers.

Note: Please wrap your code in

tags so that it looks nice and properly formatted 😀

Example:
```
#include<stdio.h>

int main()
{

printf("%d",printf("computer"));

return (0);

}
```

and also write some tricky program as reply😀..
```

{
  int i;

  for(i=0;i<5;i++)
    {

Well i' value will be printed 5 times.
1010101010(as no space and newline demand in your program).

check the output of this code :

#include<stdio.h>

int main()
{
  int i;

  for(i=0;i<5;i++);
    {
      int i = 10;
 
        printf("%d",i);

I think this thread is to give output of tricky codes, whereas in other one we have to give solutions for problems.
Here is another one:
Give the output of the following program:
```
#include<stdio.h>
int main() {
int i=1;
for(i=1,j=5;i<5;i++,j--)
{
  printf("%c  %c\n",i,j);    
}
}
```

@#-Link-Snipped-# I guess multiple declaration of i=1 won't be allowed.

and %c (meant for characters) is not valid format specifier for printing integers.
So I guess the above program will give a wierd o/p.

Actually I used C++ compiler so that multiple declaration didn't gave error (but will give error in C compiler)😁. So it's edited 👍.

And u have to guess that weird o/p 😀

a number printed in %c format specifier would get converted to it's equivalent character in terms of ascii codes.So it might be a sort of symbols.

Correct me if i'm wrong.

check the output of this code :

#include<stdio.h>

int main()
{
static   int i;

  for(i=0;i<5;i++);
    {
      static int i = 10;

        printf("%d",i);
    }
  return (0);

#-Link-Snipped-#Â
I think that i'll give a compile time error because the variable j is not declared
#include<stdio.h> int main(){ int i=1; for(i=1,j=5;i<5;i++,j--) { printf("%c %c\n",i,j); } }
