Which flag is used to stop the assembler from taking the assembly code?
Recall the following command that gives the assembly code as an output generated by the compiler:
gcc -S add.i -o add.sWhat is the extension of the object file?
the extension of the object file is .o.
Consider the following program with the line numbers:
1. #include <stdio.h>
2. #define MAX 1000
3.
4. int main() {
5. // print the maximum value
6. printf(“Maximum value allowed is %d”, MAX);
7. // return zero
8. return 0;
9. }Which lines in the above program are changed or removed by the preprocessor?
The preprocessor will completely remove lines 1, 2, 5, and 7 and it will update line 6 by replacing MAX with 1000. The resultant program looks like the following:
int main() {
printf(“Maximum value allowed is %d”, 1000);
return 0;
}Fill in the blank
