1. Find as many issues as possible and correct them

char *GenerateRandomString(void)
{
 int i;
 char RandomString[10];
 for(i = 0; i <= 10; i++)
 {
 RandomString[i] = rand() % 256;
 }
 return RandomString;
}

2. Find as many issues as possible and correct them

malloc(n) allocates n bytes in the heap.
 
int main(void)
{
 int *ptr = (int *) malloc(10);
 for(int i =0; i <10; i++)
 {
 *ptr++ = i;
 }
 free(ptr);
}

3. What is wrong with this code?

#define SQUARE(x) x*x
4. Explain the following function.
void dsp_func(
 DSPfract *ip, 
 DSPshort io,
 DSPfract *op, 
 DSPshort oo,
 DSPfract *vp,
 DSPfract *cp,
 DSPshort m,
 DSPshort n)
{
 DSPfract *s, a;
 int i, j;
 
 s = op;
 for (i = 0; i < m; i++)
 {
 for (j = 0; j < n; j++)
 {
 a = -(*vp++) * (*cp++) * 2;
 a -= (*vp++) * (*cp++);
 a += (*ip) * (*cp++);
 a += (*vp++) * (*cp++) * 2;
 a += (*vp) * (*cp++); 
 *vp = *(vp - 1);
 varptr--;
 *vp-- = *ip;
 *op = a;
 *vp = *(vp - 1);
 vp--;
 *vp = *op;
 ip += io;
 op += oo;
 cp -= 5;
 }
 op = s;
 ip = op;
 io = oo;
 cp += 5;
 vp += 4;
 }
}
