Could you specify what exactly you need in “Getting Started with C – Part 3”?

Are you looking for:
 Advanced concepts in C? (e.g., pointers, memory allocation)
 Practical coding exercises?
 File handling, data structures, or algorithms?
 Debugging techniques in C?

Let me know your focus, and I’ll provide the best content!

Great! Let’s continue with Getting Started with C – Part 3. If you’re following along from Part 1 and Part 2, you likely already covered:

Part 3: Control Flow in C

In this part, you’ll learn how to control the flow of execution in a C program using:

  1. Conditional Statements

  2. Loops

  3. switch Statement

1. Conditional Statements

if, else if, and else

c

#include <stdio.h>

int main() {
int num = 10;

if (num > 0) {
printf(“Positive number\n”);
} else if (num < 0) {
printf(“Negative number\n”);
} else {
printf(“Zero\n”);
}

return 0;
}

Use comparison operators like ==, !=, <, >, <=, >= to form conditions.

2. Loops

while Loop

c

#include <stdio.h>

int main() {
int i = 0;

while (i < 5) {
printf(“%d\n”, i);
i++;
}

return 0;
}

for Loop

c

#include <stdio.h>

int main() {
for (int i = 0; i < 5; i++) {
printf(“%d\n”, i);
}

return 0;
}

do...while Loop

c

#include <stdio.h>

int main() {
int i = 0;

do {
printf(“%d\n”, i);
i++;
} while (i < 5);

return 0;
}

3. switch Statement

Used when you have multiple values to check for a single variable:

c

#include <stdio.h>

int main() {
int day = 3;

switch (day) {
case 1:
printf(“Monday\n”);
break;
case 2:
printf(“Tuesday\n”);
break;
case 3:
printf(“Wednesday\n”);
break;
default:
printf(“Another day\n”);
}

return 0;
}
