I'm currently following a tutorial for initializing the winsock struct, but it uses "#include<" instead of a usual "#include" statement. I'm wondering what the difference is and if the distin...
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 statement. The return 0; statement inside the main() function is the "Exit status" of the program. It's optional.
Code Input #include int main () { int x = 10, *y, **z; y = &x; z = &y; printf ("%d %d %d", *y, **z, * (*z)); return 0; } Output y contains the address of x so *y print 10 then **z contains address of y of x so print the value of x 10 and 3rd * (*z) contains address of y of x that's why print 10. So, final output is 10 10 10.
Given the following program: # include <stdio.h> int main ( ) { int arr [10], i; int *p_arr; for (i = 0; i < 10; i++) arr [i] = i; p_arr = &arr [0]; for (i = 0; i < 10; i++) { printf ("%d -- %d \n", *p_arr, *p_arr * *p_arr); p_arr++; } return (0); } a) Step through the code and indicate the output of the program.

Consider the following C program: #include<stdio.h> int main() { int i, j, k = 0; j ... The number of times printf statement is executed is _______.
Make up function names, and use parameters from the existing code. #include <stdio.h> /* Terry Harvey CISC105-20 TA: Liric Waterchard*/ int main () { int someData [100] = {1,2,3,4,5,6,7}; int one = 5; ... 18. (4 pts) Write a prototype for a function that can change any element in someData. Do not write the definition. 19.
19. What will be the output of the program? #include int main() { char j=1; while(j < 5) { printf("%d, ", j); j = j+1; } printf("\n"); return 0; }
We know that a++ is post increment and in post-increment we first assign then increment.when first time while loop execute, while (0<5) the printf function contains \\n which acts as a backslash escape character. Therefore it prints 0\n in the first loop, 1\n in the 2nd loop, 3\n in the 3rd loop and so on. 5.
