Rewrite each of the 5 functions below, but only using a limited form of C. The limitations are:

1. Array syntax [ ] is not allowed 2. You may not use the keywords "for", "while", or "do". Instead, you will use "goto" (see below) 3. The body of an "if" statement must consist of only a single "goto" statement 4. No "else" statements are allowed 5. You may not use the modulus operator %. All other arithmetic operators are allowed. Use of the assignment operator is permitted. Use of bitwise and shift operators is encouraged. ---------------- goto statements Many of you have probably never used a goto statement, although it is part of the C language. The syntax is: goto ; Statements in C may be labeled. The label is an identifier followed by a ":", preceding the statememnt. For example: L1: x = 0; Below is an example of a function which is written to conform to these specifications. int factorial(int x) { int answer = 1; int i = 2; L1: if (i > x) goto L2; answer *= i; i += 1; goto L1; L2: return answer;
