How to Read and Print an Integer Value in C

1. Printing Integer values in C

Approach:

1. Store the integer value in the variableOfIntType x.
2. Print this value using the printf() method. The printf() method, in C, prints the value passed as the parameter to it, on the console screen. 

Syntax:

printf("%d", variableOfIntType);

Below is the C program to print the integer value:

• C

// C Program to Print // Integer value #include <stdio.h>   // Driver code int main() {     // Declaring integer     int x = 5;       // Printing values     printf("Printing Integer value %d", x);     return 0; }

Output

Printing Integer value 5

2. Reading Integer values in C

Approach:

1. The user enters an integer value when asked.
2. This value is taken from the user with the help of the scanf() method. The scanf() method, in C, reads the value from the console as per the type specified. 
3. For an integer value, the X is replaced with the type int. The syntax of the scanf() method becomes as follows then: 

Syntax:

scanf("%d", &variableOfIntType);

Below is the C program to read integer values in C:

• C

// C program to take an integer // as input and print it #include <stdio.h>   // Driver code int main() {     // Declare the variables     int num;       // Input the integer     printf("Enter the integer: ");     scanf("%d", &num);       // Display the integer     printf("Entered integer is: %d", num);       return 0; }

Output:

Enter the integer: 10
Entered integer is: 10

Integer Promotions in C

Some data types like char , short int take less number of bytes than int, these data types are automatically promoted to int or unsigned int when an operation is performed on them.
