Identify the error(s), if any, in the following C code snippets and correct them: 1+2 a. char gpa scanf("%c", gpa); printf("%c", gpa); b. char name[5]; name = 'Dhaka'; printf("%c", name) 4. Suppose, a 2D array of 3*3 dimension is given like below- 4 1 2 3 4 5 6 7 8 9 Develop a C code to replace the even numbers of the 2D array with * and odd numbers with @. Your final output will be like- @ * @ * @ * @ * @ 5.
