Question
Please Explain to me how you got to this point.
Much appreciated.
Here is a function, with descriptions of its supposed to do. They are incorrectly implemented. Replace the incorrect implementations of this function with correct ones that use recursion in a useful way: your solution must not use the keywords while, for, or goto. You must not use global variables or variables declared with the keyword static, and you must not modify the function parameter lists. You must not use any references or pointers as parameters except for the parameters representing arrays. //Returns the number of occurrences of digit in the decimal //representation of num. digit is an int between 0 and 9 //inclusive. ////Pseudocode Example: //countDigit(18838, 8) = > 3 //countDigit(55555, 3) = > 0 //countDigit(0, 0) = > 0 or 1 (either if fine) // int countDigit(int num, int digit) { return -1;//This is incorrect. } |Explanation / Answer
main.c
#include <stdio.h>
int countDigit(int num, int digit)
{
if(num > 0)
{
return countDigit(num / 10,digit) + (num % 10 == digit);
}
else
{
return 0;
}
}
int main()
{
int number,digit;
int count;
printf("Enter a positive integer number: ");
scanf("%d",&number);
printf(" Enter a digit whose count need to be find out: ");
scanf("%d",&digit);
count=countDigit(number,digit);
printf(" Total count of digit in number is: %d ",count);
return 0;
}
Output :-
