Write a recursive function in C that converts a number into a string
- by user3501779
I'm studying software engineering, and came across this exercise: it asks to write a recursive function in C language that receives a positive integer and an empty string, and "translates" the number into a string. Meaning that after calling the function, the string we sent would contain the number but as a string of its digits.
I wrote this function, but when I tried printing the string, it did print the number I sent, but in reverse.
This is the function:
void strnum(int n, char *str)
{
if(n)
{
strnum(n/10, str+1);
*str = n%10 + '0';
}
}
For example, I sent the number 123 on function call, and the output was 321 instead of 123.
I also tried exchanging the two lines within the if statement, and it still does the same. I can't figure out what I did wrong. Can someone help please?
NOTE: Use of while and for loop statements is not allowed for the exercise.
