Explanation :<\/h3>\n\n\n\n\n- Input Section<\/strong>:\n
\n- The program prompts the user to enter two numbers and the desired operation.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
- Switch-Case Structure<\/strong>:\n
\n- The
switch<\/code> statement checks the operation input by the user.<\/li>\n\n\n\n- Each case corresponds to an arithmetic operation:\n
\n- Addition<\/strong>: For
+<\/code>, it adds the two numbers.<\/li>\n\n\n\n- Subtraction<\/strong>: For
-<\/code>, it subtracts the second number from the first.<\/li>\n\n\n\n- Multiplication<\/strong>: For
*<\/code>, it multiplies the two numbers.<\/li>\n\n\n\n- Division<\/strong>: For
\/<\/code>, it checks for division by zero before performing the operation.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n\n\n\n- Output<\/strong>:\n
\n- The result is printed in a formatted manner using
printf<\/code>.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\nExamples :<\/h3>\n\n\n\n\n- Example 1<\/strong>:\n
\n- Input:
num1 = 10<\/code>, num2 = 5<\/code>, operation = '+'<\/code><\/li>\n\n\n\n- Output:
Result: 10.00 + 5.00 = 15.00<\/code><\/li>\n<\/ul>\n<\/li>\n\n\n\n- Example 2<\/strong>:\n
\n- Input:
num1 = 10<\/code>, num2 = 5<\/code>, operation = '-'<\/code><\/li>\n\n\n\n- Output:
Result: 10.00 - 5.00 = 5.00<\/code><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
