For each of the C++ programs shown below, write down exactly what you think the user would see as output if the program was executed.
// Program 1 #include <cstdio> int main() { printf("Welcome to question 1"); printf("\n"); return 0; } | // Program 2 #include <cstdio> int main() { printf( "Welcome to question 2"); printf( "\n"); printf( "not much,"); printf( "but more than question 1."); printf( "\n"); printf( "Bye!"); printf( "\n"); return 0; } | // Program 3 #include <cstdio> int main() { float Pi = 3.14; float radius = 4; float circumference = 2 * Pi * radius; printf( "Welcome to question 3\n"); printf( "A circle of radius %f", radius); printf( " has circumference %f\n", circumference); return 0; } |
