Write an implementation of “float stringToFloat(char *str).” The code should be simple, and not require more than the basic operators (if, for, math operators, etc.). • Assumptions • Don’t worry about overflow or underflow • Stop at the 1st invalid character and return the number you have converted till then, if the 1st character is invalid return 0 • Don’t worry about exponential (e.g. 1e10), instead you should treat ‘e’ as an invalid character • Write it like real code, e.g. do error checking • Go though the string only once • Examples • “1.23” should return 1.23 • “1a” should return 1 • “a”should return 0
