End of Question1
Program:
#include <stdio.h>
int main(void) {
int i, j, a = 0, b = 1, temp = 1;
for (i = 1; i <= 4; i++) {

b = temp;
if (i == 4 && j == 3) { // Skips the 4th character of the base
break;
}
}

Explanation: This prints the Fibonacci series in a right angle triangle formation where the base has only three characters.

End of Question3
Program:
#include <stdio.h>
int main(void) {
int prnt;
int i, j, k, r, s, sp, nos = 3, nosp = 2; //nos n nosp controls the spacing factor
// Prints the upper triangle

}
for (j = 1; j <= i; j++) {
if (i == 5 && j == 5) { //Provides the extra space reqd betn 9 n 10

printf("%2d", prnt);
}
}
if ((i % 2) != 0) {
printf("\n");
nos--;

// Prints the lower triangle skipin its base..

if ((k % 2) != 0) {
for (sp = nosp; sp >= 1; sp--) {
printf(" ");
}

prnt = k + r;
printf("%2d", prnt);
}
}
if ((k % 2) != 0) {
printf("\n");
nosp++;
}
}
return 0;
}
Explanation: This is a diamond formation composed of numbers. The numbers are in the following order next_no=i+j where
next_no = The next no to be printed
i = index of the outer for loop
j = index of the inner for loop
next_no = The next no to be printed
i = index of the outer for loop
j = index of the inner for loop
End of Question4
Program:
#include <stdio.h>
int main(void) {
int i, j, k, s, p, q, sp, r, c = 1, nos = 13;
for (i = 1; c <= 4; i++) {
if ((i % 2) != 0) { // Filters out the even line nos.
for (j = 1; j <= i; j++) { // The upper left triangle
printf("%2d", i);
}
for (s = nos; s >= 1; s--) { // The spacing factor
printf(" ");
}
for (k = 1; k <= i; k++) { // The upper right triangle
printf("%2d", i);
}
printf("\n");
nos = nos - 4; // Space control
++c;
}
}
nos = 10; // Space control re intialized
c = 1;
for (p = 5; (c < 4 && p != 0); p--) {
if ((p % 2) != 0) { // Filters out the even row nos
for (q = 1; q <= p; q++) { // Lower left triangle
printf("%2d", p);
}
for (sp = nos; sp >= 1; sp--) { // Spacing factor
printf(" ");
}
for (r = 1; r <= p; r++) { // Lower right triangle
printf("%2d", p);
}
printf("\n");
--c;
nos = nos + 8; // Spacing control.
}
}
return 0;
}
Explanation: Here we are printing only the odd row nos along with thier respective line number. This structure can divided into four identical right angle triangles which are kind of twisted and turned placed in a particular format .
End of Question5
Program:
#include <stdio.h>
int main(void) {
int i, j, k, r, s, sp, nos = 2, nosp = 1;
for (i = 1; i <= 5; i++) {
if ((i % 2) != 0) {
for (s = nos; s >= 1; s--) { //for the spacing factor.
printf(" ");
}
for (j = 1; j <= i; j++) {
printf("%2d", j-i);
}
}
if ((i % 2) != 0) {
printf("\n");
nos--;
}
}
for (k = 3; k >= 1; k--) {
if ((k % 2) != 0) {
for (sp = nosp; sp >= 1; sp--) { // for the spacing factor.
printf(" ");
}
for (r = 1; r <= k; r++) {
printf("%2d", r-k);
}
}
if ((k % 2) != 0) {
printf("\n");
nosp++;
}
}
return 0;
}
Explanation:This can be seen as a diamond composed of numbers. If we use the conventional nested for loop for its construction the numbers can be seen to flowing the following function f(x) -> j-i
where
j= inner loop index
i= outer loop index
where
j= inner loop index
i= outer loop index

if (i == 11) {
printf("7"); // Makes sure the base is printed completely
continue;
} else if (j == i) { // Hollows the rest
printf("7");
} else {
printf(" ");
}
}
printf("\n");
}
return 0;
}
Explanation: This can be seen as a hollow right-angled triangle composed of 7′s

for (j=1; j<=i; j++) {
printf("%2d",i*j);
}
printf("\n");
}
return 0;
}
Explanation: This can be seen as two right angle triangles sharing th same base
The numbers are following the following function f(x) = i *j
where
i = Index of the Outer loop
j = Index of the inner loop
The numbers are following the following function f(x) = i *j
where
i = Index of the Outer loop
j = Index of the inner loop
