how to resolve MISRA 10.3 violation?

In my C project I have use

typedef unsigned char uint8;

uint8 arry[10];

arry[5] = 'E';

but i got an MISRA violation 10.3 as "The expression is assigned to an object with a different essential type category" how to resolve this violation

thanks in advance

A "char" and a "uint8_t" have different essential type categories (see The MISRA Essential type model).

To solve your issue you need to have a "char arr[10]". Then the violation will go away.

You are giving an object of type uint8, an unsigned integer type, the value of the letter "E," which is a MISRA violation. According to MISRA C:2012 Rule 10.3, the assignment is not permitted since the character "E" belongs to a different essential type category than an unsigned integer.

There are a few options for dealing with this violation.

• One approach is to convert the object's type to a character type. To achieve this, declare the object as char rather than uint8.
• Use a cast to explicitly convert the value of the character to an unsigned integer.

typedef unsigned char uint8;
uint8 arry[10];

arry[5] = (uint8)'E';
