-The following code generates this warning because an incorrect number of arguments were used in call to `sprintf_s` and the missing argument was an integer. Had the unsafe function `sprintf` been used instead of the safer variant `sprintf_s`, this code would likely cause a stack overflow instead of just an expected output:
+The following code generates this warning because an incorrect number of arguments were used in the call to `sprintf_s` and the missing argument was an integer. Had the unsafe function `sprintf` been used instead of the safer variant `sprintf_s`, this code would likely cause a stack overflow instead of just an unexpected output:
 
 ```cpp
 void f()
 {
     char buff[8];
     char *string="Hello";
-    sprintf_s(buff, sizeof(buff), "%s %d", string);  // Attempts to print "Hello 256" or approximate, which cannot fit in the 8 char buffer
+    sprintf_s(buff, sizeof(buff), "%s %d", string);  // Attempts to print "Hello 256" or approximate, which cannot fit in the 8 char buffer. This would overflow if sprintf had been used instead
 }
