How random works? #include <stdlib.h> int r = rand(); Generates a pseudo-random number between 0 and RAND_MAX. Without seeding, the sequence is the same every run. 🌱 Seeding with srand() #include <time.h> srand(time(0)); srand() sets the starting point (seed) for rand(). time(0) and time(NULL) both give current time in seconds since 1970. Using time as a seed ensures different sequences each run. “By using the current time as a seed, we make the numbers look random every time the program runs.” Random Numbers in a Range To generate a number between min and max: ...

Create Lets create an integer array of 3 elements. Dynamic Memory behaves like an array, and its dataType specified by the type of pointer. int size = 3 * sizeof(*int); int *ptr = malloc(size); Now we can use 0,1,2 indexes to access the Memory; ptr[0] =5; // we can also use `*ptr` while default it point to 1st index(0) ptr[2] = 4; printf("%d \n", ptr[2]); We can also use calloc(3, sizeof(*ptr)) ...

Everything in a computer’s memory is stored as 0s and 1s, but why do we need to choose a data type? C Data Types In the C language, the basic data types are: char → a single character or a small number int → a whole number (integer) float → a decimal number with small precision double → a decimal number with higher precision What you’ll learn in this video: What a data type is and why it’s important Basic C data types: char, int, float, double How to choose the right data type for different values Differences between char, string, and decimal numbers Simple practical examples explained clearly
