Understand the Problem

The question is asking for explanations and examples related to various concepts in C programming, including the break statement, arrays, file modes, limitations of static arrays, ternary operators, and differences between static and dynamic arrays.

Answer

1. Exits loops/switch. 2. Stores elements. 3. Returns string length. 4. Modes: 'r', 'w'. 5. Fixed size. 6. `condition ? result1 : result2`. 7. Static: fixed, dynamic: resizable. 8. `FILE *fptr = fopen("filename", "mode");`
  1. The break statement exits loops or switch statements. Example:
for(int i = 0; i < 10; i++) { 
  if(i == 5) 
    break; 
}
  1. An array stores multiple elements of the same type. Example:
int numbers[5] = {1, 2, 3, 4, 5};
  1. strlen() returns the length of a string.

  2. Two modes to open a file:

    • 'r' (read mode)
    • 'w' (write mode)
  3. Limitations of static arrays:

    • Fixed size
    • Potential memory waste
  4. Syntax of the ternary operator:

condition ? result1 : result2;

Usage example:

int max = (a > b) ? a : b;
  1. Static arrays have a fixed size; dynamic arrays can be resized during runtime.
  2. Syntax to open a file:
FILE *fptr = fopen("filename", "mode");

Example:

FILE *fptr = fopen("data.txt", "r");

  1. Static arrays have a fixed size; dynamic arrays can be resized during runtime.
  2. Syntax to open a file:
FILE *fptr = fopen("filename", "mode");

Example:

FILE *fptr = fopen("data.txt", "r");

More Information

The break statement is useful for stopping loops early, such as when a condition is met. Arrays are a foundational data structure in C, useful for spatial locality and predictable memory allocation.

Tips

Common mistakes include forgetting to properly define array sizes or attempting to use break outside of loops or switch statements.
