What do you use to enclose a block of conditional statements?

To enclose a block of conditional statements in C, braces are used. Braces, denoted as curly brackets ({}), define the start and end of a block of code, which is essential for grouping multiple statements that should be executed together based on the outcome of the conditional check.

In conditional statements, such as if, else, or switch, if there are multiple lines of code to be executed under a certain condition, they need to be enclosed within braces to ensure that they are treated as one cohesive block. Without braces, only the first statement following the conditional would be executed if the condition is true, leading to potential logical errors in the program.

Other symbols like parentheses are used in C for expressions or method calls, square brackets are primarily reserved for array indexing, and angle brackets are used for template definitions or including files. Thus, braces are specifically the proper choice for enclosing blocks of statements in control flow constructs.
