SUMMARY

The discussion centers on modifying the declaration of the pointer s1 to ensure that the strcpy function successfully copies the string from s2 to s1. The solution involves allocating stack memory for s1 using an array declaration, such as char s1[100];, which provides sufficient space for the string. This approach prevents memory wastage while ensuring that s1 points to a valid memory location on the stack.

Summary:: Question: In the blank space below, write a new version of the first line of this code segment such that the strcpy succeeds. Use only stack memory and try not to waste memory.

how can I change the first line of the code?

Code:
char *s1;       // change this line
char *s2 = "good luck";
strcpy(s1, s2); // I must succeed
