Code:#include <stdio.h>int main() { char s[1000]; scanf("%s", s);//input for string int a, b, i;//a is upper limit and b lower limit scanf("%d", &a);//getting a scanf("%d", &b);//getting b for(i=b; i<b; i++){ printf("%s", s[i]);//printing sliced string } return 0; }
> int a, b, i;//a is upper limit and b lower limit
So how about
int toIndex, fromIndex, i;
Then check whether your code still makes sense.
Single letter identifiers are OK for loop subscripts such as i,j.
But everything else should have a meaningful name.
for(i=fromIndex; i<fromIndex; i++)
I think that fails on the very first comparison.
> printf("%s", s[i]);
You need "%c" format to print single characters.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
The program runs after changing the format specifier but nothing prints on the screen, and thanks for the tip!
Notice that you forgot to use the variable named a. That's why Salem suggested a rename to toIndex and fromIndex: it would make your mistake more obvious, e.g.,
Code:for(i=fromIndex; i<fromIndex; i++){

Thanks! Didn't noticed.
