List of 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
