C Programming Quiz 1 Printf Scanf Data Types Type Modifiers Writing to memory pointer by an uninitialized pointer invokes undefined behaviour. either allocate enough memory: pointers = malloc(256); if(!pointers) perror("malloc"); else scanf("%255s", pointers); or declare it as a static array: char pointers[256]; you should also consider using fgets () instead of scanf (). 11.1 introduction a pointer is a derived data type in c. pointers contains memory addresses as their values. a pointer is a variable whose value is the address of another variable, i.e., direct address of the memory location. like any variable or constant, you must declare a pointer before using it to store any variable address. Pointer arithmetic provides an alternative to array indexing in c. the two statements: ptr = a 1; and ptr = &a[1]; are equivalent and would assign the value of 404 to ptr. Arrays and pointers given discrete data y f(x i) integrate fo int main(void) { for (i=0; i<=n; i ) scanf(“%f”,&y[i]); *reading f(x i)* integral =0.5*(y[0] y[n]); for(i=1; i
