void is used when you are not required to return anything from the function to the caller of the function.. for eg. void no_return_fn() { cout<< "This function will not return anything" << endl; return; // returns nothing or void } int is used when you have to return an integer value from the function to the caller of the function. for eg.
The output of the following C program is _____. C void f1 (int a, int b) { int c; c=a; a=b; b=c; } void f2 (int *a, int *b) { int c; c=*a; *a=*b;*b=c; } int main() { int a=4, b=5, c=6; f1(a, b); f2(&b, &c); printf ("%d", c-a-b); return 0; } A Computer Science portal for geeks. It contains well written, well thought and well explained ...
Given the function definition void something ( int a, int& b ) {int c; c = a + 2; a = a * 3; b = c + a;} ... A simplified version of a function which is used to test the main program is called. a stub. In the following function, what is passed to the first parameter? void f1( int& value1, int value2); ...
What is the difference between the parameters of the following code: void duplicate (int& a, int& b, int& c) void duplicate (int a, int b, int c) By qualifying them as const, the function is forbidden to modify the values of neither a nor b, but can actually access their values as references (aliases of the arguments), without having to make ...
These int and void are its return type. Void means it will not return any value, which is also ok. But if want to know whether the program has terminated successfully or not, we need a return value that can be zero or a non-zero value. Hence the function becomes int main() and is recommended over void main().
Consider the following program written in C syntax: void swap(int a, int b) {int temp; temp = a; a = b; b = temp;} void main() {int value = 2, list[5] = {1, 3, 5, 7, 9};
1. What will be the output of following program? #include int main() { int a = 5, *b, c; b = &a; printf("%d", a * *b * a + *b); return (0); } Options: 1. 130 2. 103 3. 100 4. 310 The answer is the option(1). Explanation: Here the expression a**b*a + *b uses pointer in C
"int main() is the preferred style for subjective, cosmetic reasons" - perhaps subjective, ok, but IMO it's still just right. is clearly an empty tuple.(void) looks like it's a single argument of type void, and then you'd expect to be able to write stuff like main(f()), if f is a function that "returns void". It's a good idea to make a distinction between empty sets (/lists/arrays ...
In C/C++ the default return type of the main function is int, i.e. main() will return an integer value by default. The return value of the main tells the status of the execution of the program. The main() function returns 0 after the successful execution of the program otherwise it returns a non-zer
Step 1: Define the City class. Let us first define the City class, which will be used to store information about each city as an object. A City object will have three fields: "country" refers to the code of the country the city is in, "name" refers to the name of the city, and "population" refers to the number of people in the city.
