Learn the syntax and examples of the C if else statement, a conditional statement that allows you to execute different codes depending on the value of a condition.
The switch statement transfers control directly to an executable statement within the body, bypassing the lines that contain initializations. The following examples illustrate switch statements: C Copy switch( c ) { case 'A': capital_a++; case 'a': letter_a++; default : total++; } All ...
The following examples illustrateswitchstatements: C switch( c ) {case'A': capital_a++;case'a': letter_a++;default: total++; } All three statements of theswitchbody in this example are executed ifcis equal to'A', since nobreakstatement appears before the followingcase. Execution control is...
By this way, we do not need to use write values with separate cases, if the values that you want to validate are in range and want to execute the same body (set of statements), we can use switch statement with the case values in a range....

Note:If there isonly one statementis present in the “if” or “else” body then you do not need to use the braces (parenthesis). For example the above program can be rewritten like this: #include<stdio.h>intmain(){intage;printf("Enter your age:");scanf("%d",&age);if(age>=18)...
switch (expression) { case constant1: // statements break; case constant2: // statements break; . . . default: // default statements } How does the switch statement work? The expression is evaluated once and compared with the values of each case label. If there is a match, the cor...
