| 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
Dont 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
Dont 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
ashould return 0
