Question
what is the ouput for *q and z[2][1]
Analyze and determine the outputs of the following program statements:
#include <stdio.h>
#include <math.h>
int main()
{
float a-3, c=4, *p, *q;
int i, j, k, n=3, b=3,w=2;
float
float y[4]={1,2,3,4};
x[3][4]={9,8,1,2,3,4,5,6,7,8,9,10}, z[4][3];
for(i=0; i<4; i++)
{ for(j=0; j<3; j++)
}
z[2][1] x [2] [1];
q=&z [2] [1];
printf("*q= %.2f\n", *q*2);
for(i=0;i<3; ++i)
{c+=y[i]-1;
}
else
{
z[j][i]=x[i][j];
if(w<10)
{p-&n;
p+=i;
printf("a=%0.2f\n c= %0.2f\n z[2][1] =%0.2f \n", a, c, z[2][1]);
i=4; j=3;k-n-1;
if (i!-jj-3)
{i=k;j-j+i;}
else if(i<8)
{w=n+i+j+1+y[j]; w=n+a+k+2+y[i]; }
}
a+=y[i]+b;
}
printf("w=%d", w+5);
printf("w=%d\n",w-5);}
