Casue: 

This warning is triggered by a printf or scanf format specifier that is not appropriate for the type of the variable being printed.

Example: 

#include <stdio.h>

int main() {
   long int li = 0;
   printf("%l\n",li);     // %l is the size specifier; the type specifer is missing
   printf("%ld\n",li);  // OK
   return 0;
}

#include <stdio.h> main() { size_t a; printf("Enter the value of a:"); scanf("%Iu",&a); printf("%#Ix",a); } Gives me this warning messages... size.c(6): warning #269: invalid format string conversion scanf("%Iu",&a); ^ size.c(7): warning #269: invalid format string conversion printf("%#Ix",a); ^ output is fine but i want to get rid of this warning message...Is there a way? I used the above format specifiers based on this url-- http://msdn.microsoft.com/en-us/library/tcxf1dw6.aspx

which version of the Intel C++ compiler are you using and which VC? I do not get this warning with 10.1 or 11.x.

8.1 version is very old. please upgrade to 11.0. This issue is fixed in the 10.1 and newer release. Or you can try the Parallel Composer.
