problem with printf function?

Question

i wrote the following program

 #include 

 main()
 {
 int i = 2;
 float c = 4.5;
 printf(\"%d\\n\",c);
 printf(\"%f\\n\",i);
 return 0;
 }
         


        

Answer 1

Basically, format controls replace the placeholder according to specified data type.

• %d expects argument of type int
• %f expects argument of type double

So Good way of doing this is

#include 

int main(){
   int i = 2;
   float c = 4.5;
   printf("%d\n",i);
   printf("%f\n",c);
   return 0;
}
