Unexpected output of printf

Question

int a=5;
float b=3.5;
printf(\"%d\",b);
printf(\"\\n%f\",a);

Can anyone please tell me why this code is showing unexpected output (garbage\\n3.5)

Answer 1

Because the a variable is a int type, while your are specifying a format string for a float type, and vice versa for the variable b.

Note :

%d is for integer type

%f is for float type

You should use :

int a=5;
float b=3.5;
printf("%f",b);
printf("\n%d",a);
