Print a string N number of times in C++
By Karandeep SinghHey, guys today we are going to learn how to print a string N number of times in C++. We can print a string N number of times with the help of iteration statements also known as loops. Before starting with the program lets discuss iteration statements.
Iteration statements / Loops
Iteration statements are used to execute a statement or a block of statements multiple numbers of times depending on the condition specified. In other words, loops execute a block of given statements repeatedly until the specified condition is true. Iteration statements involve ‘initialisation’, ‘test expression’ and ‘updating expression’. 3 iteration statements used in C++ are :
- for loop: This entry controlled loop iterate the block of statement a specific no of times.Syntax:
for(initialisation;test_expression;updating_expression) { statements; } - while loop: This entry controlled loop iterates the block of statements. It is mostly used when the number of iterations is not known beforehand. more info Its syntax is:
initalisation;
while(test_expression)
{
statements;
updating_expression;
}- do-while loop: This is an exit controlled loop which means it executes the statement block once even if the test expression is false. Its syntax is:
initialisation;
do{
statements;
updating_expression;
} while(test_expression);Program to print a string N number of times using for loop
#include <iostream>
using namespace std;
int main()
{
int N;
cout<<"Enter the value of N";
cin>>N;
for(int i=1;i<=N;i++)
{
cout<<"Hello, Have a nice day "<<endl;
}
return 0;
}Output:
Enter the value of N 2 Hello, Have a nice day Hello, Have a nice day
C++ Program to print a string N number of times using while loop
#include <iostream>
using namespace std;
int main()
{
int N;
cout<<"Enter the value of N";
cin>>N;
int i=1;
while(i<=N)
{
cout<<"Hello, Have a nice day "<<endl;
i+=1;
}
return 0;
}Output:
Enter the value of N 3 Hello, Have a nice day Hello, Have a nice day Hello, Have a nice day
Program to print a string N number of times using do-while loop
#include <iostream>
using namespace std;
int main()
{
int N;
cout<<"Enter the value of N";
cin>>N;
int i=1;
do
{
cout<<"Hello, Have a nice day "<<endl;
i+=1;
}while(i<=N);
return 0;
}Output:
Enter the value of N 4 Hello, Have a nice day Hello, Have a nice day Hello, Have a nice day Hello, Have a nice day
