List of Format Specifiers in C

The list of format specifiers in C covers the different data formats of variables that are read with the scanf() function to read data and printed with the printf() function. The list of format specifiers in c contains several data formats for data types such as char, string, int, float, double, long, short, long int, short int, unsigned, octal, hexadecimal and so on. The scanf(), printf() functions are used to format the data using the format specifiers in C.

C Language has many format specifiers. A variable with a data type can be printed using different format specifiers. For example, a integer variable can be printed as decimal number, octagonal number and hexadecimal number.

List of Format Specifiers in C

The following example illustrates how to print a variable with different format specifiers.

#include <stdio.h>

int main(int argc, char** argv) {
	int a = 15;
	float b = 12345.12345;
	printf("int value   : %d\n", a); 
	printf("oct value   : %o\n", a); 
	printf("hex value   : %x\n", a); 
	printf("hex value   : %X\n\n", a); 
	
	printf("float value : %f\n", b); 
	printf("float value : %e\n", b); 
	printf("float value : %E\n", b); 
	printf("float value : %G\n", b); 
	
	return 0;
}

Output

int value   : 15
oct value   : 17
hex value   : f
hex value   : F

float value : 12345.123047
float value : 1.234512e+004
float value : 1.234512E+004
float value : 12345.1
