How to write A Java program to print number of digits in a given number?
One way to do this is to convert the number to a String, then use the corresponding String method to find out the length of the String.
What program can be written to count the number of alphanumerics in a string?
public int getStringLength(String val) { return val.length(); } There is an inbuilt functionality in strings that counts the number of alphabets in a string called length()

How do you write c program to accept a string from the console and count number of vowels constants digits tabs and blank spaces in a string?
Read the characters one at a time, and write an "if" for each of the cases. In each case, if the condition is fulfilled, increment the corresponding counter variable.
Why pointer is used to reference a string of characters write C plus plus statements that display the text hello using pointer to a string notation?
We use a pointer to reference a string because a string is an array of characters where every element is a char (or a wchar_t if using UNICODE strings). Passing arrays by value would require the entire array to be copied, but passing a pointer variable to an array only copies the pointer, which is effectively the same as passing the array by reference. #include <iostream> int main() { char * psz = "hello"; // pointer to a null-terminated string. std::cout << psz; // pass the pointer (by value) to the insertion operator. return( 0 ); }

What is cputs function in computer c plus plus?
Nothing.The C language only recognizes a few keywords, like "for" and "if". Most of what's in a C program ... that doesn't reference routines in the C program itself ... are library calls, and cputs() is one of those. What it does is write its argument (which should be a pointer to a character string) to the console... console put string.
In C programming what is pointer?
Simply put, a pointer is a memory address. It "points" to data at that address. The Data Type of the pointer tells the program how to interpret the data at the address. For example, a character pointer will read the data at the address as a byte and interpret it as a character (like an ASCII character, for instance). A string pointer is just like a character pointer, except that it starts reading characters at the address and keeps going until it encounters a null (a data value of zero). The "string" of characters is interpreted as text. The available data types include just about anything you can imagine. Intrinsic types, structures, functions... in later versions of C, pointers can point to objects.
How to write a program in python to print the reverse of a number?
In python, type the following into a document. NOTE: Sentences following a # symbol are comments, and are not necessary for the program to run. #!/usr/bin/python #This program takes a input from a user and reverses it. number = input("Type a number: ") #This takes input from a user. a = len(number) #This finds the length of the number reverse = "" #This sets the variable reverse to an empty string. for i in number: a = a-1 #The places in a string start from 0. The last value will be the length minus 1.reverse = reverse + number[a] #Makes the number's last digit the new string's first. print("The reverse of", number, "is", reverse + ".") #prints the resulting string. This program will take any sequence of characters and reverse them. The final value is a string, but if an integer is needed, one needs only to add the line reverse = int(reverse) above the print statement. However, this will stop the program from being able to reverse strings, as it is not possible to convert a string to an integer if it is not a number.
