Discover What is Fibonacci series in C, a technique that involves calling a function within itself to solve the problem. Even know how to implement using different methods.
In this blog, you will learn about functions in C programming, including their definition, types, and how to use them to make your code more modular and efficient.
{ int numbers[5] = {10, 20, 30, 40, 50}; printf("The first number is %d\n", numbers[0]); // Output: 10 return 0; } In this example, we create an array called numbers with five integer values. We access the first element of the array using numbers[0]. Keep up the great...

C - printf() Specifier for double Is there a printf() converter to print in binary format? C - Nested printf() printf() Vs. puts() printf() Vs. sprintf() %d Vs. %i format Specifiers C - Single Character Input & Output C- Formatted Input & Output ...
printf("offsetof(struct int_and_char, c) = %zu\n", offsetof(struct int_and_char, c)); // Prints: offsetof(struct int_and_char, c) = 4 // You may wonder whether union field offsets are guaranteed to be 0. The // answer is YES: // // "... A pointer to a union object,...

Format string overflow: In programming languages, when the format string function is used to generate character strings and the format string is customized by users, attackerscanforge the format string and use the features of the *printf() series functions to snoop on the content in the stack ...
sigaction(sig, act, oact) means “set the disposition for sig to act, and store the old disposition in oact”. Its return value is 0 or -1, indicating whether the system call errored.Those struct sigactions are “dispositions”, meaning they express what to do when the given signal is ...
printf("%d\n", **dptr); // Accessing value of var through double pointer How Double Pointers Differ from Single Pointers The primary difference between single and double pointers is the level of indirection. While a single pointer directly points to the data, a double pointer points to a po...
