What is a syntax - error ? Give an example of a syntax error in a C - program.

Syntax errors: Errors that occur when you violate the rules of writing C/C++ syntax are known as syntax errors. This compiler error indicates something that must be fixed before the code can be compiled. All these errors are detected by the compiler and thus are known as compile-time errors.

  • Missing Parenthesis (})
  • Printing the value of a variable without declaring it
  • Missing semicolon like this :

// C program to illustrate syntax error

#include<stdio.h>

void main()

{

int x = 10;

int y = 15;  

printf("%d", (x, y)) // semicolon missed

}

 What is a String? Write a function in C for string concatenation. Without the use of an inbuilt string function. String A string is a data type used in programmings, such as an integer and floating-point unit, but is used to represent text rather than numbers. It is comprised of a set of characters  that can also contain spaces and numbers. For example, the word "hamburger" and the phrase "I ate 3 hamburgers" are both strings. Even "12345" could be considered a string, if specified correctly. Typically, programmers must enclose strings in quotation marks for the data to recognized as a string and not a number or variable name . String concatenation in C C program to concatenate two strings, for example, if the two input strings are "C programming," and " language" (note the space  before language), then the output will be "C programming language." To concatenate the strings, we use strcat function of string.h, to concatenate ...

 What is the scope of a Variable? Explain the difference between global and local variables with example programs. A scope in any programming is a region of the program where a defined variable can have its existence and beyond that variable, it cannot be accessed. There are three places where variables can be declared in C programming language − Inside a function or a block which is called  local  variables. Outside of all functions which are called  global  variables. In the definition of function parameters which are called  formal  parameters. Let us understand what are  local  and  global  variables, and  formal  parameters. Local Variables Variables that are declared inside a function or block are called local variables. They can be used only by statements that are inside that function or block of code. Local variables are not known to functions outside their own. The following example shows how local variables are u...

What is a Pointer? Write a C program using a pointer to print the name and price of the items sold in a retail shop on a specific date.  Pointers in C are easy and fun to learn. Some C programming tasks are performed more easily with pointers, and other tasks, such as dynamic memory allocation, cannot be performed without using pointers. So it becomes necessary to learn pointers to become a perfect C programmer. Let's start learning them in simple and easy steps. #include <stdio.h> int main () { int var1 ; char var2 [ 10 ]; printf ( "Address of var1 variable: %x\n" , & var1 ); printf ( "Address of var2 variable: %x\n" , & var2 ); return 0 ; } What are Pointers? A  pointer  is a variable whose value is the address of another variable, i.e., direct address of the memory location. Like any variable or constant, you must declare a pointer before using it to store any variable address. The general form of a pointer v...
