What is the meaning of percent s in C programming?

Answer 1

%d is used as a format mask to represent an integer.

Any of the "formatted" io functions can use this: printf, fprintf, scanf, etc.

Example:
int i = 0;
printf("%d", i); // prints the value of i
This is a format specifier which is used to identify that the given input is an integer or not
In C: c%d means the remainder dividing c with d

in printf/scanf format string: %d means an integer data
For extracting or inserting data which is signed integer in decimal format

Answer 2

s,d,f,etc are all data types in a c program and you need % to define it in scanf and printf what is the difference between s and %s, s is just a variable whereas %s is a data type denoting a sting.for example you can just enter scanf("%s",name)which gets a string called name

Answer 3

The %s token is a format specifier used in strings to designate the insertion point for a string variable. Other tokens include %c (character), %d (integer), %f (floating point value), %x (hexadecimal value) and so on.

Answer 4

The %c token is a format specifier used in format strings, as used by the printf() and scanf() family of functions:

char x;

printf ("Enter a character: ");

scanf ("%c", &x);

printf ("The character '%c' has the ASCII character code %d\n", x, (int) x);
