The if statement will check if a condition is true or false. If condition is true then the next statement or a block of statements are executed. If the condition is false then the statement or statement block is skipped. A statement block is a set of statements enclosed in curly braces.
The if statement is written as
if (condition) statement;or
if (condition) {
statement-block;
}
if (count < 5) printf("The count is %d",count);
if (count < 5) {
printf("The count is %d",count);
count=count+1;
}The if ... else statement will evaluate the condition and execute one set of statements if the condition is true or an alternate set of statement if the condition is false.
The if ... else statement is written as
if (condition) statement1; else statement2;or
if (condition) {
statement_block1;
}
else {
statement_block2;
}
if (count > 5) {
printf("Count is greater than 5");
}
else {
printf("Count is not greater than 5 \\n");
printf("Please input new value for count \\n");
scanf("%d",&count);
}
