Yes, here are a few examples:
using the if statement:
if (condition)
statements
Using the while statement:
while (condition)
statements
Using if and else statement:
if (condition)
statements
else
statements
Statements that check an expression then may or may not execute a statement or group of statements depending on the result of the condition.
The only way that can happen is if a condition is both true and false at the same time. There is no such condition, so either the if or the else statements will execute for a given condition, but never both.

Unconditional statements are statements that are invoked unconditionally. Conditional statements have a controlling expression, while unconditional statements do not. For example: void f (bool b) { if (b==true) do_something(); // conditional statement (controlled by the expression b==true) do_something_else(); // unconditional (executes regardless of b's value) }
Selection control statements in C++There are basically two types of control statements in c++ which allows the programmer to modify the regular sequential execution of statements.They are selection and iteration statements. The selection statements allow to choose a set of statements for execution depending on a condition. If statement and switch statement are two statements which allow selection in c++. There is also an operator known as conditional operator which enables selection.If statementSyntax : if (expression or condition){ statement 1;statement 2;}else{ statement 3;statement 4;}The expression or condition is any expression built using relational operators which either yields true or false condition. If no relational operators are used for comparison, then the expression will be evaluated and zero is taken as false and non zero value is taken as true. If the condition is true, statement1 and statement2 is executed otherwise statement 3 and statement 4 is executed. Else part in the if statement is optional. If there is no else part, then the next statement after the if statement is exceuted, if the condition is false. If there is only one statement to be executed in the if part or in the else part, braces can be omitted.Following example program implements the ifstatement.// evenodd.cpp# include # include void main(){int num;cout
Control statements are statements that alter the flow of execution according to the evaluation of an expression (the condition). The C++ control statements are ifstatements, switch statements and the tertiary conditional operator, ?:.
Statements that check an expression then may or may not execute a statement or group of statements depending on the result of the condition.
it is used often in the context: if(condition is true) {following statements will be executed}; else[meaning that if the above condition is not true] {following statements will not be executed} for example: if(x == 3) {cout<< "condition is true"; y=4;} else {cout<< "condition is not true"; y=x-1}
The only way that can happen is if a condition is both true and false at the same time. There is no such condition, so either the if or the else statements will execute for a given condition, but never both.
There is no difference. Both statements are invalid.
My self Dhilib... it is a simple query. if statement is a basic control statement. mostly it used in all the languages. also in c plus plus syntax: if(test condition) { true statements; } else { false-statements; } Example: void main() { int a,b; a=54; b=65; if(a>b) { cout<<" a value is big"; } else { cout<<"b value is big"; } }
x = 12;
Unconditional statements are statements that are invoked unconditionally. Conditional statements have a controlling expression, while unconditional statements do not. For example: void f (bool b) { if (b==true) do_something(); // conditional statement (controlled by the expression b==true) do_something_else(); // unconditional (executes regardless of b's value) }
Decision making statements make use of conditional expressions. In C++ there are three possibilities: if/else, switch/case and the ternary operator (?:).
Writing programs in it.
Control instructions are instructions that alter the flow of execution. In C++ this include if, if-else statements, switch-case statements and the conditional ternary operator (?:), as well as loop structures (for, while, do-while) and procedural goto statements.
