Concept explainers

Declaring and Defining the function

A set of statements, which performs a particular task is called a function. The program gains modularity by using function. The application is quite easy to understand, read, and edit when they are created with functions. The developer/programmer creates a function and uses main() to call the function. Once the function gets executed, the control is transferred to the main program.

Question

In C program

Hint: Use function isdigit(str[0])to find out if str[0]is numeric.

int count(char ch, const char "st)
int ans;
if (st(0] == 10)
ans = 0;
else
* simple case /
* redefine problem using recursion /
if (ch == str(0]) frst character must be counted /
ans =1+ count(ch, &str[1]);
else
" first character is not counted /
ans = count(ch, &str[1);
return (ans);

Process by which instructions are given to a computer, software program, or application using code.

For function decToBinary, write the missing parts of the recursion case. This function should return a string that stores the binary equivalent for int variable num. Example: The binary equivalent of 13 may be found by repeatedly dividing 13 by 2. So, 13 in base 2 is represented by the string "1101". Examples: decToBinary(13) -> "1101" public String decToBinary (int num) { if (num < 2) return Integer.toString(num); else return <<Missing recursive call>> + <<Missing calculation>>;}

For example, we have the sequence:1, 1, 2, 3, 5, 8, 13, 21…Write your own recursive code to calculate the nth term in the sequence. You should accept a positive integer as an input, and output the nth term of the sequence.Once you have created your code, add comments describing how the code works, and the complexity of any code you have created.

in C programing Write a recursive function that returns 1 if an array of size n is in sorted order and 0 otherwise. Note: If array a stores 3, 6, 7, 7, 12, then isSorted(a, 5) should return 1 . If array b stores 3, 4, 9, 8, then isSorted(b,4) should return 0.int isSorted(int *array, int n){
Recursive Copy Function Given a string str and number n, write a program that recursively appends a copy of string str n times and returns the resulting string.

You should end up with n+1 copies of the str total in the output because you are appending additional str copies. Use string literal formatting for the output.
