C - Basics and Execution Environment

#include <stdio.h>
int main() {
    printf("Hello!\n");
    printf("Welcome to C.\n");
    return 0;
}

#include <stdio.h>
int main() {
    printf("Hello!Welcome to C.\n");
    return 0;
}

#include <stdio.h>
int main() {
    printf("Hello!");
    printf("Welcome to C.\n");
    return 0;
}

#include <stdio.h>
int main() {
    printf("Hello!");
    printf("Welcome to C.");
    return 0;
}

Step-by-Step Solution

Solution:

Step 1: Understand how to print two lines
Each line should end with a newline character \n to move to the next line.
Step 2: Check each option for correct newlines
#include int main() { printf("Hello!\n"); printf("Welcome to C.\n"); return 0; } prints "Hello!" with \n and "Welcome to C." with \n, so two lines appear.
Final Answer:
Two printf statements, each ending with \n -> Option A
Quick Check:
Use \n at end of each line for separate lines [OK]

Quick Trick: Use \n after each line to print on new lines [OK]
