Study Notes
Purpose of Break Statement in C
- The
breakstatement in C terminates the execution of the innermost loop or switch statement it is currently inside. - It jumps the control flow outside the loop or switch block.
- It is often used alongside conditional statements (
if,else) to stop iteration when a specific condition is met.
Syntax of a while Loop in C
- The
whileloop is a pre-test loop that executes the code block repeatedly as long as the condition remains true. - General syntax:
while (condition) {
// Code to be executed repeatedly
}
-
conditionis a boolean expression that is evaluated before each iteration. - If the condition is true, the loop iterates again; otherwise, the loop terminates.
C Code Example of Nested Loop
#include <stdio.h>
int main() {
for (int i = 1; i <= 3; i++) {
for (int j = 1; j <= 3; j++) {
printf("%d ", i * j);
}
printf("\n");
}
return 0;
}
- This C code demonstrates a nested loop with an outer
forloop and an innerforloop. - The inner loop executes fully for each iteration of the outer loop, resulting in a table-like output.
Decision-Making Statements in C
-
if-elsestatement: It executes a block of code only if a specific condition is true. If the condition is false, an optionalelseblock executes. -
switch-casestatement: It provides a more efficient way to execute different code blocks based on the value of an expression. It checks the value of a variable or expression against multiplecaselabels.
Function of Break within Loops in C
- When
breakis encountered inside a loop, the loop is immediately terminated. - Control flow jumps to the statement immediately after the loop.
- It is useful for scenarios where you want to stop the loop prematurely, such as when a specific condition is satisfied.
