Iteration Statements across Different Languages
Here, we will see the implementation of different iteration statements in different programming languages.
1. Iteration Statements in C:
C supports all the three loops: for, while and do-while loop. Below is the implementation of all types of iteration statements in C:
#include <stdio.h>
int main()
{
// For Loop
for (int i = 0; i < 5; i++) {
printf("%d ", i);
}
printf("\n");
// While Loop
int count = 0;
while (count < 5) {
printf("%d ", count);
count++;
}
printf("\n");
// Do-While Loop
count = 0;
do {
printf("%d ", count);
count++;
} while (count < 5);
printf("\n");
return 0;
}
Output
0 1 2 3 4 0 1 2 3 4 0 1 2 3 4
2. Iteration Statements in C++
C++ provides support for all the common loops like: for, while, and do-while loops. Below is the implementation of all types of iteration statements in C++:
#include <iostream>
using namespace std;
int main()
{
// For Loop
for (int i = 0; i < 5; i++) {
cout << i << " ";
}
cout << endl;
// While Loop
int count = 0;
while (count < 5) {
cout << count << " ";
count++;
}
cout << endl;
// Do-While Loop
count = 0;
do {
cout << count << " ";
count++;
} while (count < 5);
cout << endl;
return 0;
}
Output
0 1 2 3 4 0 1 2 3 4 0 1 2 3 4
3. Iteration Statements in Python:
Python supports for and while loops. It does not have a native do-while loop. But same thing can be achieved using while loop with a break condition. Below is the implementation of all types of iteration statements in Python:
# For Loop
for i in range(5):
print(i, end=" ")
print()
# While Loop
count = 0
while count < 5:
print(count, end=" ")
count += 1
print()
count = 0
while True:
print(count, end = " ")
count += 1
if count >= 5:
break
Output
0 1 2 3 4 0 1 2 3 4 0 1 2 3 4
4. Iteration Statements in Java
Java provides support for all the commonly used loops: for, while and do-while loop. Below is the implementation of all types of iteration statements in Java:
/*package whatever //do not write package name here */
import java.io.*;
class GFG {
public static void main(String[] args)
{
// For Loop
for (int i = 0; i < 5; i++) {
System.out.print(i + " ");
}
System.out.println();
// While Loop
int count = 0;
while (count < 5) {
System.out.print(count + " ");
count++;
}
System.out.println();
// Do-While Loop
count = 0;
do {
System.out.print(count + " ");
count++;
} while (count < 5);
System.out.println();
}
}
Output
0 1 2 3 4 0 1 2 3 4 0 1 2 3 4
5. Iteration Statements in C#:
C# provides support for all the commonly used loops: for, while and do-while loop. Below is the implementation of all types of iteration statements in C#:
using System;
public class GFG {
static public void Main()
{
// For Loop
for (int i = 0; i < 5; i++) {
Console.Write(i + " ");
}
Console.WriteLine();
// While Loop
int count = 0;
while (count < 5) {
Console.Write(count + " ");
count++;
}
Console.WriteLine();
// Do-While Loop
count = 0;
do {
Console.Write(count + " ");
count++;
} while (count < 5);
Console.WriteLine();
}
}
Output
0 1 2 3 4 0 1 2 3 4 0 1 2 3 4
5. Iteration Statements in JavaScript:
JavaScript provides support for all the commonly used loops: for, while and do-while loop. Below is the implementation of all types of iteration statements in JavaScript:
// For Loop
for (let i = 0; i < 5; i++) {
console.log(i);
}
// While Loop
let count = 0;
while (count < 5) {
console.log(count);
count++;
}
// Do-While Loop
count = 0;
do {
console.log(count);
count++;
} while (count < 5);
Output
0 1 2 3 4 0 1 2 3 4 0 1 2 3 4
Iteration statements, commonly known as loops, are fundamental constructs in programming that enable repetitive execution of code blocks based on specified conditions. Understanding and utilizing these loops effectively is crucial for implementing repetitive tasks efficiently, reducing code redundancy, and enhancing the overall clarity and maintainability of the code.
Iteration Statements in Programming
Iteration statements, commonly known as loops, are statements in programming used to execute part of code repeatedly based on condition or set of conditions. These constructs are important for performing repetitive tasks efficiently. In this article, we will discuss various types of iteration statements and their use in different programming languages.
