What is Nested For Loop? Describe Flow Diagram and give an example?

Nested Loop:

           The loop within a loop is called Nested loop. In nested loops the inner loop is executed completely with each change in the value of counter variable of outer loop. The nesting can be done upto any level. The increase in level of nesting increases the complexity of nested loop.

Flow Diagram:

Example:

#include <iostream>

#include <math.h>

using namespace std;

int main()

{

for (int i=1;i<=3;i++)

{

for(int j=1;j<=3;j++)

cout << i <<"\t"<<j<<endl;

}

        return 0;

}

Reverse the value of Entered Number

write a program that reverse the value of given number like 12345 and program should output 54321
#include <iostream>
#include <math.h>
using namespace std;
int main()
{
int num,rev=0;
cout << "Enter an Integer: ";
cin >>num;
/*cout << "Enter The value of N: ";
cin >>n_value;*/
for (int i=num;i!=0;i=i/10)
{
rev=10*rev+i%10;
}
cout << "Entered Number is : " << num <<endl;
cout << "Reverse is: " << rev <<endl;
return 0;
}

Sum of Series

write a program that will calculate the sum of series:   x+x²+x^{3+...............}+xⁿ

#include <iostream>
#include <math.h>
using namespace std;
int main()
{
int n_value,x_value,sum=0;
cout << "Enter The value of X: ";
cin >>x_value;
cout << "Enter The value of N: ";
cin >>n_value;
for (int i=1;i<=n_value;i++)
{
sum=sum + pow(x_value,i);
}
cout << "Sum is: " << sum <<endl;
return 0;
}

Sum of Squares of Integers

//Write a program to calculate the sum of squares of integers 1 to n. where n is the value entered by user. i.e(sum=1²+2²+3²+4²+5^{2................}n²).

#include <iostream>
using namespace std;
int main()
{
int num,sum=0;
cout << "Enter The value of n: ";
cin >>num;
for (int i=1;i<=num;i++)
{
sum=sum+(i*i);
}
cout << "Sum is: " << sum <<endl;
return 0;

Prime or Composite With "bool" data type using NOT operator.

//3rd logic with NOT Logical Operator and bool Data Type.
#include <iostream>
#include <process.h>
using namespace std;
int main()
{
int n;
bool check=false;
cout << "Enter Any +ve Integer: ";
cin >> n;
if (n < 0)
{
cout << "STOP !!!! Plz Enter Correct Number Value."<<endl;
exit(1);
}
for (int j=2;j<=n/2;j++)
{
if (n%j==0)
{
check=true;
break;
}
}
if (check!=true)
cout << n << " is a Prime Number.\n";
else
cout << n << " is a Composite Number.\n";
return 0;
}

Prime or Composite........

// 2nd Logic To check prime or composite
#include <iostream>
#include <process.h>
using namespace std;
int main()
{
int n,counter=0;
cout << "Enter Any +ve Integer: ";
cin >> n;
if (n < 0)
{
cout << "STOP !!!! Plz Enter Correct Number Value."<<endl;
exit(1);
}
for (int j=2;j<=n/2;j++)
{
if (n%j==0)
{
counter++;
break;
}
}
if (counter==0 && n!=0)
cout << n << " is a Prime Number.\n";
else
cout << n << " is a Composite Number.\n";
return 0;
}

int num,count=0;
cout<<"Enter a Number to Check prime or not:  ";
cin>>num;
if (num < 0)
{
cout << "Plz Enter +ve Integer Value"<<endl;
exit(1);
}
for(int a=1;a<=num;a++)
{
if(num%a==0)
{
count++;
}
}
if(count==2)
{
cout<<num<<" is a Prime Number. \n";
}
else
{
cout<<num<<" is Composit Number. \n";
}
return 0;
