FAQs on Data Types in C++ - 2 Video Lecture - Crash Course for EmSAT Achieve
| 1. What is the float data type in C? |  |
Ans. The float data type in C is used to store single-precision floating-point numbers. It can represent numbers with fractional parts and a range of values, but with less precision compared to double data type.
| 2. How is the float data type different from the double data type in C? | |
Ans. The float data type in C occupies 4 bytes of memory and provides a precision of about 6 decimal places. On the other hand, the double data type occupies 8 bytes of memory and provides a precision of about 15 decimal places. This means that the double data type offers higher precision than the float data type.
| 3. How to declare and initialize a float variable in C? | |
Ans. To declare and initialize a float variable in C, you can use the following syntax:
float variable_name = value;
For example, float temperature = 98.6;
| 4. Can a float variable store integers in C? | |
Ans. Yes, a float variable in C can store both integers and numbers with fractional parts. However, when storing integers in a float variable, they are automatically converted to floating-point numbers.
| 5. What are some common operations that can be performed on float variables in C? | |
Ans. Some common operations that can be performed on float variables in C include addition, subtraction, multiplication, division, and comparison. These operations can be done using arithmetic operators such as +, -, *, /, and relational operators such as >, <, ==, etc.
