if(fp != NULL) /*file opened successfully */
return 0;
else
return 1;
}
Answer 23:
===========
void writeToFile(FILE *fp, int arr[], int size)
{
int i;
for(i = 0; i < size; i++)
{
fprintf(fp, "%d\n", arr[i]);
}
fclose(fp);
}

write a function called readAny having the following declaration: void readAny(fstream &iofile, char buffer[], int size, int start, int index); with five parameters, iofile is the fstream variable for reading the file. Assume that the file has already been opened. buffer is the character array for returning the bytes that will be read in by the function. size specifies how many bytes to read in. start will have one of three constants 1, 2, or 3. 1 means from the...

in C++ and also each function has its own main function so
please do the main function as well. Previously when i asked the
question the person only did the function and didn't do the main
function so please help me do it.

Write a C++ function, lastLargestIndex that takes as parameters an int array and its size and returns the index of the "last occurrence" of the largest element in the array. Include another function to print the array. Also, write a program to test your function. [HINTS) Create an array of size 15 in the main function and initialize it with the values shown in the below sample output. Pass the array and its size to function lastLargestindex; function lastLargestindex returns...
Write a c program that finds the uncommon elements from two array elements using pointers only .

C programming only please 5.2.3: Printing array elements with a for loop. Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards, then backwards. End each loop with a newline. Ex: If courseGrades = {7, 9, 11, 10}, print: 7 9 11 10 10 11 9 7 Hint: Use two for loops. Second loop starts with i = NUM_VALS - 1.
