Build the compiler in the src/ directory using the following commands
cd src/
make
./bcc <test file>
bcc is the compiler executable file. Use it to compile any code written in flatB language.
The language consists of 2 blocks, declaration block and codeblock . The declaration block consists of all the variable declarations and it's mandatory that all variables have to be declared in the declaration block before using them in the codeblock. The codeblock everything else other than variable declarations.
declblock {
// All variable declarations go here
}
codeblock{
// Main logic of the program ( shouldnot include variable declarations)
}
- Variable Declarations
int data, array[100];
int sum;
- For Loop
for i = 1, 100 {
.....
}
for i = 1, 100, 2 {
..... // Value of i varies from 1 to 100 with step size 2.
}
for i = expr1, expr2, expr3 {
..... // Value of i varies from expr1 to expr3 with step size expr3
}
- if-else statement
if expression {
....
}
if expression {
...
}
else {
....
}
- while statement
while expression {
}
- conditional and unconditional goto
got label
goto label if expression
- IO Statements
print "blah...blah", val
println "new line at the end"
