Nested if Statement 2

3. BLOCKS if ( studentGrade >= 60 ) cout << "Passed.\n"; else {
cout << "Failed.\n";
cout << "You must take this course again.\n"; }

4. Nested If
if condition within a if condition is called Nested if

5. Nested If #include <iostream.h> #include<conio.h> main() {
int code;
cout<<"enter the vlaue of code";
cin>>code;
if(code>1)
cout<<“ ";
else
if(code<1)
cout<<"\n ";
cout<<"\n ";
getch(); }

6. Nested If if condition within a if condition is called Nested if
if ( x > 5 )
if ( y > 5 )
cout << "x and y are > 5";
else
cout << "x is >= 5";
============================================= { }
cout << "x is <= 5";

7. IF Condition (scenarios)
if (a == b)  {
  if (b <= 3)
    x = 4;
  else
    x = 0; }
 else
  if (a > b)
    x = a;
     x = b;
if a is given as 5, b is given as 5
(Answer: 0)
if a is given as 2, b is given as 2
(Answer: 4)
(Answer: 5)
if a is given as 5, b is given as 2
if a is given as 2, b is given as 7
(Answer: 7)

8. IF Condition (multiple scenario)
Example 2. According to the values given, what will be the value of x after each of the following?
if a is given as 2, b is given as 5
(Answer: 10)
x = 5; if (a < b)           if (a < 10)                x = x + 3; x = x + 2;
if a is given as 15, b is given as 20
(Answer: 7)
if a is given as 3, b is given as 3
(Answer: 7)

9. IF Condition (multiple scenario)
Trace the following and show the output
int a,b,c;
a=3;
b=-5;
if(a<2*b) {
b=a;
c=b;
cout<<c; }
else
if (b>0)
b=0;
cout<<b;

10. IF Condition (multiple scenario)
Trace the following and show the output

11. #include<conio.h>
#include<iostream.h>
main() {
      int a,b,c;
      cout<<"Enter first number: ";
      cin>>a;
      cout<<"Enter second number: ";
      cin>>b;
      cout<<"Enter third number: ";
      cin>>c;   
      
            if(a>b)
            {
                     if(a>c)
                     {
                      cout<<a<<"  is biggest number";
                     }
                      else
                     {
                        cout<<c<<"  is biggest number";
           }       
      else
      {
                     if(b>c)
                     cout<<b<<"  is biggest number";
                     else
                     cout<<c<<"  is biggest number";
      }
       getch();

12. Write a Program that prompt the user to enter the vlaue for variable a, b and c. Code the program based on condition written in left column of the table and print corresponding value written in right column of the table (Only use Nested if Condition.
