std::ostream& alternate (std::ostream& os, const std::string& str) {
for (size_t index=0; index<str.size(); index+=2) os << str[index];
return os;
}
int main (void) {
std::string test {"The quick brown fox jumps over the lazy dog"};
alternate (std::cout, test);
std::cout << std::endl;

Are spaces taken as single character in a string?
public class count { public static void main(String[] args) { String string = "1 2 3 4"; char[] array = string.toCharArray(); System.out.println("Number of characters in string: " + string.length()); System.out.println("Number of characters in array: " + array.length); } } Output: Number of characters in string: 7 Number of characters in array: 7 So yes, spaces are taken as single characters in a string.
How are the unrecognized character within the control string interpreted in printf function?
In the printf function in C, unrecognized characters within the format string are treated as literal characters. This means that any character that doesn't match a format specifier (like %d, %f, etc.) will be printed as-is in the output. For example, if the format string is "Hello %d!" and the integer value is 5, the output will be Hello 5!. Characters that are not part of a format specifier will simply appear in the output without any special formatting.

A program of c plus plus to accept the string and display the alternate characters in reverse order using pointer?
The following program prints every second character of the input in reverse order. #include<iostream> #include<sstream> int main() { std::cout << "Input:\t"; std::string input = ""; std::getline (std::cin, input); if (input.size()) { std::cout << "Output:\t"; unsigned index = input.size() / 2 * 2; do { index -= 2; std::cout << input[index]; } while (index); std::cout << std::endl; } }
How do you use MID function in qbasic?
...QBASIC program code... name$="Jack" startCharPos%=2 howManyChars%=2 PRINT MID$(name$,startCharPos%,howManyChars%) ...output... ac EXPLANATION The MID$() function allows you to select characters from out of a string. In the above case the string is,... name$="Jack" ...where... J= string position 1 a= string position 2 c= string position 3 k= string position 4 ...thus, if we select MID$(name$,2,2)... ...this code is actually saying...select from the name...the character which begins at position 2 = a/and, extract 2 characters going along from there... = ac.

How do you display a text reversely in C language without using onlu simply input and output?
#include<stdio.h> #include<conio.h> void main() { char string[20]; int i=0; printf("Enter the string.\n"); while(i<=19) { scanf("%c",&string[i]); i++; } while(i>=0) { printf("%c",string[i]); i--; } getch(); } In this program it is compulsory to enter 20 characters. Now we can write a program in which it is not necessary. #include<stdio.h> #include<conio.h> #include<string.h> void main() { char string[20]; int length; printf("enter the string.\n"); gets(string); length=strlen(string); length--; while(length>0) { printf("%c",string[length]); length--; } getch(); }
What elements are in string?
A string is an array of characters.
Is java's println a method?
Consider the following statement: System.out.println ("string to be printed"); The statement begins with System.out. This is a constant that represents the default output mode, which in this case is the screen. The constant helps to read and display the data in a Java program. The output is generated using the built-in println() method. The string that is assigned to the println() method is displayed when the statement is executed. For example, class Class2 { public static void main (String args[]) { System.out.println("Here is your string"); } } The above program will show the following output: Here is your string
How do you Print all the first characters in the string in python programming?
Let's say your string is a variable called "string" To print out all the characters in order, you would do: for i in string: print(string[i]) If you wanted to print out characters up to a point (n = maximum characters): for i in range(n): print(string[i]) hope this helps!
Count characters in an input string using c sharp?

How do you get value of a string in reverse order in c?
Assume C#, not C: Traditional way: public string Reverse(string s) { if (string.IsNullOrEmpty(s)) return s; // "" or null char[] characters = s.ToCharArray(); Array.Reverse(characters); return new string(characters); } or as an extension method: public static string Reverse(this string s) { if (s == "") return ""; char[] characters = s.ToCharArray(); Array.Reverse(characters); return new string(characters); } The differences of the 2 methods above is on the caller (how to use Reverse()), and they may co-exist: For example: string test = "abc"; string result1 = Reverse(test); // traditional way string result2 = test.Reverse(); // call the extension
