Common Errors in C Programming

Syntax errors in C programming

#include 

int main() {
    int a, b, c;
    a = 2
    b = 3;
    c = a + b;
    printf("The sum of a and b is %d", c);
    return 0;
}

Semantic errors in C programming

#include 

int main() {
    int a, b, c;
    a = 2;
    b = 3;
    c = a - b;
    printf("The sum of a and b is %d", c);
    return 0;
}

Runtime errors in C programming

Runtime errors are errors that occur during the execution of a program. A program with runtime errors can compile successfully, but unexpected events or situations may cause the program to crash or result in incorrect output when executed. Some common examples of runtime errors are:

• Division by zero
• Null pointer dereferencing
• Array index out of bounds
• Resource leaks (e.g., memory or open file handles)

Examples of Errors in C Programming and Their Solutions

In this section, we will dive into examples of common errors encountered in C programming and discuss their solutions.

C programs with errors and solutions: Case Studies

Let's look at some case studies to demonstrate how to identify and handle common errors in C programming.

#include 

float square(float number) {
    return number ^ 2;
}

int main() {
    float num, result;
    printf("Enter a number: ");
    scanf("%f", #);
    result = square(num);
    printf("The square of %f is %f.", num, result);
    return 0;
}
