You have an int array with n elements and a structure with three int members. ie struct No { unsigned int no1; unsigned int no2; unsigned int no3; }; Point1.Lets say 1 byte in the array element is represented like this - 1st 3 bits from LSB is one number, next 2 bits are 2nd no and last 3 bits are 3rd no. Now write a function, struct No* ExtractNos(unsigned int *, int count) which extracts each byte from array and converts LSByte in the order mentioned in point1.and save it the structure no1, no2, no3. in the function struct No* ExtractNos(unsigned int *, int count), first parameter points to the base address of array and second parameter says the no of elements in the array. For example: if your array LSB is Hex F7 then result no1 = 7, no2 = 2, no3 = 7. In the same way convert all the elements from the array and save the result in array of structure.

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
