7.Fibonacci series without recursion
ReplyDelete#include < stdio.h >
#include < conio.h >
int main()
{
int initial_value=0; int final_value=1,temp_value,count=10;
// count contains the number of elements to be generated.....
for(count=1;count<=10;count++)
{
temp_value=initial_value+final_value;
printf("\n%d",initial_value);
initial_value=final_value;
final_value=temp_value;
}
getch();
return 0;
}
1.Word Count in a sentence
ReplyDeleteLogic:-The logic behind this program is checking if the character in the sentence is a 'blank' and with the conditions that the next is not a blank character, or current character position is not equal to length of the sentence. If so, variable 'words' is incremented by one as one new word found.
#include < stdio.h >
#include < conio.h >
int main()
{
char str[50];
int words = 0, len = 0, i;
printf("\n\n\t ENTER A STRING...: ");
gets(str);
while(str[len]!='\0')
len++;
len--;
for(i=0;i <= len;i++)
{
if ( ( str[i] == ' ' && str[i+1] != ' ' ) || i == len )
words++;
}
printf("\n\t NUMBER OF WORDS IN THE ABOVE SENTENCE IS...: %d", words);
getch();
return 0;
}
3.Stack Direction---------
ReplyDeleteThe following program creates an integer (a) on the stack, then passes a pointer to a down to the function sub. sub creates another integer on the stack (b), then compares the address of a to the address of b. If b’s address is greater then a’s, then the stack is growing up, if it’s less, then it’s growing down.
#include
void sub(int *a) {
int b;
if (&b > a) {
printf("Stack grows up.");
} else {
printf("Stack grows down.");
}
}
main () {
int a;
sub(&a);
}
NOTE-------------
Why can’t we declare two integers in the main() function and check if the stack grows up or down? Any reason for creating a separate sub() function?
Ans:Which integer of the two would we expect to be higher / lower in this case? I’m not sure there’s anything to say they would go into main’s stack frame in a particular order, especially if the compiler is trying to optimise (but I’m no expert).
With the sub function, we know for sure that the second integer will be in a different stack frame, which must be either higher or lower (and hence everything in it will be higher or lower).
