This document discusses different types of conditional statements used in programming. It defines conditional statements as statements used to execute or ignore code based on a test of conditions. The types discussed include if statements, if-else statements, nested if statements, and switch statements. Examples are provided for each to demonstrate their usage, along with examples of how these conditional statements map to real-life scenarios. Pseudocode programs are also included to demonstrate how each statement would be written.

- 3. The topic we’ll present >>> What conditional statements ? What is Types conditional statements? If statements with example If else statement with example Nested if with example Switch Loop
- 4. What is conditional? The conditional statement are used to execute the or (ignore) a set of statement after testing the a condition The condition statement are also called selection statement
- 5. Usage of conditional statement in life ? I am learning c, c++ I am confuse how it work in real life In programming each function have a reason Lets say about conditional statement A user going to signing up for Facebook bout we don't want the users signing up of age less than 15 years old. If user age is less than 15 it should terminate the sign up page and give a reason saying “sorry your too Young” Here we use if else statement behind situation
- 6. If statement ? If statement is used to execute or ignore a set of statement after testing the condition Syntax if(condition) Statement -1; Statement -2;
- 7. Program of If Statement?
- 8. If else statement ??
- 9. Program of If-else statement??
- 10. If –else statement example in real life?? If it id raining I shall not water the plants , else I have to water the plants. now we can write it in pseudo code If (raining == true) Do not water Else Do water
- 11. Nested if statement Nested if When an if statement is used within another if statement it is called nested statement. If the condition-1 is true then the control shift to the next if statement and the condition-2 is tested If the condition-2 is true then the statement-2 is execute The control will pass to statement -3 and this statement will execute If the condition-2 is false thestatement-2 is skipped and the control shift to the statement-3 and it will execute. Syntax: If (condition-1) { If (condition-2) { statement-2 } Conditon-3
- 12. Example of nested if in real life If a boy age is more the 18 if his nationality was Afghan than he can give the vote in election now we change it in pseudo code if (age>18) { if (nationality ==‘Afghan’) cout<<“you Can Give the Voten”; } else Cout<<“you can not give the vote”;
- 13. Program of nested if Void main() { In a,b,c; Cout<<“enter first valuen”; Cin>>a; Cout<<“enter the 2nd valuen”; Cin>>b; Cout<<“enter the 3rd valuen” Cin>>c; If(a==b) { If(a==c) Cout<<“these values are equaln”; } else cout<<“these value are differents”;
- 14. What is switch Statement ? Switch statement is use when a multiple choice are given and one choice be selected. When the switch statement is executed the given expression is first evaluate and then value returned by the expression is compared with the values of the constant given in each case if the value match with co- nstant value of a case then the statement of that case are execute Keyword default is also used in the body of the switch if no case matched then the statement default are execute Break statement Break statement is used to exit from the body of the switch
- 15. example of switch in Real life ? Let a company allows you a family tour, but the budget is not confirmed yet so, you would pre-plan the tour ? For this based on number of family member ready for this tour ,you would collect information for the tour expense of different destination and later on, select which one suits to your budget
- 16. What is syntax of switch Statement ? Switch(expression) { Case constant-1; Statements; Break; Case const-2; Statements; Break; Case const-3; Statements; Default Statements; }
- 17. Program of switch statement?
- 18. What is Loop?
