In this tutorial, we will discuss the concept of C++ code to Read and print string of one dim array
In this topic, we are going to learn how to read and print strings of a one dimensional array in C++ programming language using loops.
In this blog, We have already discuss that “What is an array“, type of arrays and how to access it
Arrays are the special type of variables to store Multiple type of values(int, string,char, etc)under the same name in the continuous memory location. we can be easily accessed using the indices(indexes)
Here,
Program 1
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
char str[20];
cout<<"Enter your name\n";
cin>>str;
cout<<"\nyou entered:\n"<<str<<endl;
getch();
return 0;
}
When the above code is executed, it produces the following result
Enter your name: Kamalakumar You entered : Kamalakumar
Program 2
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
char str[20];
cout<<"Enter your name\n";
cin.get(str,20);
cout<<"\nCheck your name:\n"<<str<<endl;
getch();
return 0;
} When the above code is executed, it produces the following result
Enter your name: Kamalan Check your name: Kamalan
In this program, we are briefing input strings of an array and then print them using for loop in C++ language
Program 3
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
string str[20];
int len;
cout<<"\nEnter array length\n";
cin>>len;
cout<<"Enter students name\n";
for(int i=0; i<len; i++){
cin>>str[i];
}
cout<<"\nEntered students names are:\n";
for(int i=0; i<len; i++){
cout<<str[i]<<"\n";
}
getch();
return 0;
}
When the above code is executed, it produces the following result
Program 4
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
string str[20];
// one D array declaration
int len;//Declare variable for length
cout<<"Enter array length\n";
//Ask input from the user for length
cin>>len;
//Reading the input for length
cout<<"\nEnter students name\n";
//Ask enter the student name
for(int i=0; i<len; i++){
cout<<"Enter the string"<<" str=["<<i<<"]: ";
cin>>str[i];
}//Enter the students name using for loop
cout<<"\nEntered students names are:\n";
for(int i=0; i<len; i++){
cout<<"Your entered string is:"<<" str=["<<i<<"]: ";
cout<<str[i]<<"\n";
//Display the students name
}
getch();
return 0;
}
When the above code is executed, it produces the following result
In this program, we are briefing input strings of an array and then print them using while loop in C++ language
Program 5
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
string str[20];
int len;
cout<<"Enter array length\n";
cin>>len;
cout<<"\nEnter students name\n";
int i=0;
while(i<len){
cin>>str[i];
i++;
}
cout<<"\nEntered students names are:\n";
int j=0;
while(j<len){
cout<<str[j]<<"\n";
j++;
}
getch();
return 0;
}
When the above code is executed, it produces the following result
Program 6
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
string str[20];
//String array declaration
int len;
//Variable declaration - integer
cout<<"Enter array length\n";
//Ask input for array length
cin>>len;
//Reading the array length
cout<<"\nEnter students name\n";
int i=0;
while(i<len){
cout<<"Enter the string"<<" str=["<<i<<"]: ";
cin>>str[i];
i++;
}//Enter the student name using while loop
cout<<"\nEntered students names are:\n";
int j=0;
while(j<len){
cout<<"Your entered string is:"<<" str=["<<j<<"]: ";
cout<<str[j]<<"\n";
j++;
}// Display the student name using while loop
getch();
return 0;
}
When the above code is executed, it produces the following result
In this program, we are briefing input strings of an array and then print them using Do-while loop in C++ language
Program 7
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
string str[20];
int len;
cout<<"Enter array length\n";
cin>>len;
cout<<"\nEnter students name\n";
int i=0;
do{
cin>>str[i];
i++;
}while(i<len);
cout<<"\nEntered students names are:\n";
int j=0;
do{
cout<<str[j]<<"\n";
j++;
}while(j<len);
getch();
return 0;
} When the above code is executed, it produces the following result
Program 8
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
string str[20];
int len;
cout<<"Enter array length\n";
cin>>len;
cout<<"\nEnter students name\n";
int i=0;
do{
cout<<"Enter the string"<<" str=["<<i<<"]: ";
cin>>str[i];
i++;
}while(i<len);
cout<<"\nEntered students names are:\n";
int j=0;
do{
cout<<"Your entered string is:"<<" str=["<<j<<"]: ";
cout<<str[j]<<"\n";
j++;
}while(j<len);
getch();
return 0;
}
When the above code is executed, it produces the following result
