Rendering C in MIPS: Iteration (Loops)

Iteration (e.g. while and for) Again we can map our C program to simplified C using goto statements and then map it to MIPS

                      top_while:
while (Cond) {           if(! Cond)
   Statements;           goto end_while:
}                        execute Statements
                         goto    top_while 
                      end_while:

Treat for as a special case of while

                                i = 0
for (i = 0; i < N; i++) {       while (i < N) {
    Statements;                    Statements;
}                                  i++;
                                }
