#include <stdio.h> int main(){ for(int i = 0x20; i<0x30; i++){ printf("%d ", i); printf("%c\n", i); } }

typedef struct { int x; int y; } point_t; point_t some_func(void) { point_t pt; pt.x = 0; pt.y = 0; return pt; }

Yes if (someValue == someOtherValue) { someFunction(); }

Let’s consider the integer 6. 6/2=3 6/2=3 6/2=3
-
The floatval() function return the float value of the variable passed to it. For example: $integer = 123; $float = floatval($integer); var_dump($integer); // int(123) var_dump($float); // float(123)
-
Here is the example: void foo(void) { printf(“foo was called\n”); } if you do this: foo(); then you’re calling do by name. If you do: void (*func_ptr)(void) = foo; func_ptr(); Then you’re calling foo through function pointer func_ptr().

void f(int i) { i = i + 1; } void g(int &i) { i = i + 1; } int main() { int i = 1; f(i); // by value: i is still 1 g(i); // by reference: i is now 2 return 0; }

int x[] = {1,2,3,4}; void print(int *arr, size_t n) { for (size_t i = 0; i < n; i++) { printf(“%d\n”); } } print(x, 4);

#include <stdio.h> int main() { for (int a=20;a>=10;--a){ // Write C code here printf("Hello world"); } return 0; }

int x[] = {1, 2, 3, 4}; You could also use a length: int x[4] = {1, 2, 3, 4};
