declare a float number in C

float num_float;

This code creates a float variable called ‘num_float’. A float is a specific data type of number that can contain decimals. To create a float in C, we first use the keyword ‘float’ followed by the name of the float we want to create. In this case, ‘num_float’. The semicolon at the end of the line is a must-have in C as it signals the end of the statement.
