output 2,3,3.....first time x=4 fine. y=--x, means value of x is decremented by 1 and stored in y, thus now y=3 and x is also 3. then z=x-- means value of x is stored in z( z=3) and then x is decremented i.e now x=2 but z=3. when u r printing the value, then printf() prints 2 3 3
1. What will be the output of following program? #include int main() { int a = 5, *b, c; b = &a; printf("%d", a * *b * a + *b); return (0); } Options: 1. 130 2. 103 3. 100 4. 310 The answer is the option(1). Explanation: Here the expression a**b*a + *b uses pointer in C

🙋 Introduction. The header file in C is one of the most commonly used and essential libraries. It provides functionalities for input and output operations, making it a crucial part of any C programmer's toolkit. This guide will give you an in-depth look at what offers, its key functions, and how to use them effectively.. 🎯 Purpose of
There are some less known facts in C related to octal numbers. Let us look at the below example code first. Examples: // program to show octal number interpretation #include int main() { int x = 012; printf("%d", x); return 0; } Output: 10 Surprisingly the output is not 12.
As we discussed earlier, the main function is the starting point of program execution. Operating system (OS) initiates the program execution by invoking the main function. And it will expect an integer value from the main function. That integer value represents the status of the program. That's why we declared main function return type as int.
All valid C programs must contain the main() function. The code execution begins from the start of the main() function. The printf() is a library function to send formatted output to the screen. The function prints the string inside quotations. To use printf() in our program, we need to include stdio.h header file using the #include
Keep in mind, we are incrementing the address, so now it points to the (arr+1) element in p array. That's why ptr-p returns 1. In other words, we're subtracting addresses. *ptr points to arr + 1 element. That's why the second value is also equal to 1. By doing **ptr we retrieve a value that is stored at arr+1 address and it is also 1.
