the case statement is equivalent to multiple parallel ifs. Most of everyday code is made up of " if" or "case" inside each other. if rising_edge(clk) then if enable = '1' then case .... when .... if... en
We then use the else branch of the nested if statement to capture the case when the addr signal is 1b. It is also possible for us to use an else-if type statement here but the else statement is more succinct. The behaviour is the same in both cases as the signal can only ever be...

Mechanism of if-else statement in C Initiated by the “if” keyword, the statement is enclosed in parentheses containing an evaluative condition, typically a Boolean expression capable of being true or false. When the condition enclosed within the parentheses is assessed as true, the code snippet...
A break statement is used for two purposes To terminate a loop immediately and resume at the next statement following the loop. To terminate a case in a switch statement. For example: v <- c(0:6) for (i in v) { if(i == 3){ break } print(i) } Output: [1] 0 [1] 1 [1]...
