Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Question

The Problem: strcat is unsafe
The following code overflows the array name and corrupts memory.
// Bad code
char name[10];
strncpy(name, "Oualline", sizeof(name));
name[sizeof(name)-1] = '\0';
strcat(name, ", ");
strcat(name, "Oualline);
// Memory is now corrupt
Note: Defining an array using a numeric constant (10) instead of a named
constant (NAME_SIZE) is bad programming practice. But it does make the
example simpler, so it's good writing practice when explaining a hack.

Process by which instructions are given to a computer, software program, or application using code.

Java - Functions with 1D Arrays Create a program that asks the user for the size of an integer array and the elements of the array. Then, create a function called maxArray() with the following details: Parameters: An integer array The size of the integer array Return type - int Return value - the maximum value of the integer array Call the function you created in the main and pass the integer array and its size to it. Make sure to store the return value in a variable so you could print it afterwards. Input 1. First line contains the size of the array 2. Succeeding lines are the elements of an array 3.

Assume that the integer array myScores has been declared and assigned values. Assume that the integer variable size has been declared and initialized using the number of elements in the array myScores. Write a code block that declares a pointer to an integer and initializes it using the address of the array. Use that pointer to access the array elements, compute their average (as double), and display it on the screen.
Reverse ArrayWrite a function that accepts an int array and the array’s size as arguments. The function should create a copy of the array, except that the element values should be reversedin the copy. The function should return a pointer to the new array. Demonstrate thefunction in a complete program.
//Required Functionvoid func(int array_1[],int array_2[],int size){ for(int i=0;i<size;i++){ if(array_2[i]>array_1[i]){ array_1[i]=array_2[i]; } } return;} //main function to test the function.int main(){ int size=6; int a[]={1,5,9,8,7,6}; int b[]={1,4,10,12,7,15}; printf("First array before function call: "); for(int i=0;i<size;i++){ printf("%d ",a[i]); } func(a,b,size); //call to the created function printf("\nFirst array after function call: "); for(int i=0;i<size;i++){ printf("%d ",a[i]); } return 0;} 1.
