C programming language List the results that will be produce

C programming language

List the results that will be produced if the following program were to be executed. You can indicate the results on the right hand column. #include int main() {int i; int *p[3]; int p1[]={l, 2, 3), P2[]={9, 3, 4}, P3[]={2}; char *s[2] = {\"Test 1\", \"First test\"}; p[0]=p1; p[1] =p2; p[2]=p3; printf(\" 1st Print: \ \"); for (i=0; i

Solution

The output is explained in the code as comments:

#include <stdio.h>
int main()
{
int i;
int *p[3];
int p1[] = {1, 2, 3}, p2[] = {9, 3, 4}, p3[] = {2};
  
char *s[2] = {\"Test 1\", \"First test\"};
  
p[0] = p1; //p[0] points to first element in the array p1.
p[1] = p2; //p[1] points to first element in the array p2.  
p[2] = p3; //p[2] points to first element in the array p3.
  
printf(\" 1st Print:\ \");
for(i = 0; i < 3; i++) //This loop runs for 3 values 0, 1, and 2.
printf(\"%d \", p[i][0]); //p[0][0] will print 1, p[1][0] will print 9, p[2][0] will print 2.
  
printf(\"\ \ 2nd Print:\ \");
for(i = 0; i < 3; i++) //This loop runs for 3 values 0, 1, and 2.
printf(\"%d \", p[0][i]); //p[0][0] will print 1, p[0][1] will print 2, p[0][2] will print 3.

printf(\"\ \ 3rd Print:\ \");
for(i = 0; i < 7; i++) //This loop runs for 7 values, 0, 1, 2, 3, 4, 5, and 6.
printf(\"%p \", *p); //This will print the address of the array p1.
  
printf(\"\ \ 4th Print:\ \ \");
for(i = 0; i < 3; i++)   //This loop runs for 3 values 0, 1, and 2.
printf(\"%d \", *p[i]);   //*p[0] will print 1, *p[1] will print 9, *p[2] will print 2.
  
printf(\"\ \ 5th Print:\ \");
printf(\"\ %s and %s \", s[0], s[1]); //This will print 2 strings. Test1 and First test
  
printf(\"\ \ 6th Print:\ \");
printf(\"%c in s1 and %c in s2\ \", s[0][0], s[1][0]); //This will print 2 characters. T in s1 and F in s2
  
return 0;
}

And the output is:

1st Print:

1 9 2

2nd Print:

1 2 3

3rd Print:

0x7fff50c4a704 0x7fff50c4a704 0x7fff50c4a704 0x7fff50c4a704 0x7fff50c4a704 0x7fff50c4a704 0x7fff50c4a704

4th Print:

1 9 2

5th Print:

Test 1 and First test

6th Print:

T in s1 and F in s2
