Example 5: Using ‘greater than’ operator within the IF statement. From the C99 standard: Unlike the bitwise binary & operator, the && operator guarantees left-to-right evaluation; there is a sequence point after the evaluation of the first operand. Control is transferred inside the body of the while loop. Conditional Statements in C programming are used to make decisions based on the conditions. What does this expression mean? If the value of test_condition is true (non zero value), statement(s) will be executed. Inside the While loop, we placed If Statement to test whether i is equal to 5 or 9. 1.

Syntax: for( ; ; ) {// some code which run infinite times } In the above syntax three part of the for loop that is initialize, condition and increment/ decrement is not provided, which means no start value no end condition. Each case in a block of a switch has a different name/number which is referred to as an identifier. Decision making condition statement. a group of statements enclosed by curly braces).
