![]() ![]() It incorporates an extra parameter-the maximum number of characters (including the null-terminator) to be written into the output string-which helps prevent buffer overflows by ensuring data does not exceed a specified limit. In contrast, the snprintf() function is designed with safety in mind. Writing too much data to the allocated space can lead to issues such as memory corruption or even security threats. The traditional sprintf() function lacks built-in protection against buffer overflows. The final string is: Ascii value difference of s and a is 18Īs briefly mentioned above, the main distinction between these two functions is how they deal with buffer overflow situations. The result should be the following output: The length of the buffer is: 39 Return 0 to indicate the program executed successfully ![]() Printf("The final string is: %s", buffer) Printf("The length of the buffer is: %d\n", buffer_length) Int buffer_length = sprintf(buffer, "Ascii value difference of %c and %c is %d", char1, char2, difference) Store the return value (number of characters written to the buffer) in an integer variable Assign a formatted string to the buffer using sprintf function Calculate the ASCII value difference between the two characters Declare and initialize character variables for comparison Code exampleīelow is an example demonstrating the usage of the sprintf() function in C: #include For example, if the execution fails because the output was bigger than the available buffer, sprintf returns a negative value. If the function executes successfully, it returns the number of characters written to the buffer, excluding the terminating null character. The return type of the sprintf function is int. It follows the same specifications as print().
