iOS Objective-C Basics (Retired) Fundamentals of C Variables


I need to create a float variable

Since float is an existing type of value in C, you should be able to create a new float variable merely using float to prefix the variable name and the value you want:

float my_float_value = 2.0;

The way you declare a variable in C is <type><name> = value. You can omit the value and add it later. So to declare this variable you should write float followed by the name of the variable. For example: float a;

thank you

float myfloatvalue =2.0; or float myfloatvalue; myfloatvalue=2.0;
