Question
The right way to merge the below 2 statements is?char ch;ch = (char) malloc(100);a.char ch = (char)malloc(100);b.char *ch = (char) malloc(100);c.char ch = *malloc(100);d.char *ch = (char )(malloc)(100);
Solution 1
To merge the two statements, we need to combine the declaration and assignment of the variable ch.
The correct way to merge the statements is:
char *ch = (char*) malloc(100);
This statement declares a pointer variable ch of type char* and assigns it the memory address returned by the malloc function, which allocates 100 bytes of memory.
Solution 2
To merge the two statements, we need to combine the declaration and assignment of the variable ch.
The correct way to merge the statements is:
char *ch = (char*) malloc(100);
This statement declares a pointer variable ch of type char* and assigns it the memory address returned by the malloc function, which allocates 100 bytes of memory.
Solution 3
To merge the two statements, we need to consider the correct syntax and data types. Let's analyze each option:
a. char *ch = (char*) malloc(100);
This statement correctly declares a pointer ch of type char* and assigns it the memory allocated by malloc().
b. char *ch = (char) malloc(100);
This statement is incorrect because it tries to cast the result of malloc() to a char type, which is not valid. The correct data type for the pointer is char*.
c. char ch = *malloc(100);
This statement is incorrect because it tries to assign the value pointed to by malloc() to a single char variable ch. The correct data type for the pointer is char*.
d. char *ch = (char *)(malloc*)(100);
This statement is incorrect because it tries to cast malloc* to a function pointer, which is not valid. The correct syntax for casting is (char*).
Therefore, the correct way to merge the statements is option a: char *ch = (char*) malloc(100);.
