Calculating min and max of a 2-dimensional array in c
This program is to calculate the sum, min and max of the sum of the elements of an array. The
maximum value is a problem, it is always wrong.
void main(void)
{
int degree[3][2];
int min_max[][];
int Max=min_max[0][0];
int Min=min_max[0][0];
int i,j;
int sum=0;
clrscr();
for(i=0;i<3;i++)
{
for(j=0;j<2;j++)
{
printf("\n enter degree of student no. %d in subject %d:",i+1,j+1);
scanf("%d",°ree[i][j]);
}
}
for(i=0;i<3;i++)
{
for(j=0;j<2;j++)
{
printf("\n Student no. %d degree in subject no. %d is %d",i+1,j+1,degree[i][j]);
}
}
for(i=0;i<3;i++)
{
sum=0;
for(j=0;j<2;j++)
{
sum+=degree[i][j];
}
printf("\n sum of degrees of student no. %d is %d",i+1,sum);
min_max[i][j]=sum;
if(min_max[i][j] <Min)
{
Min=min_max[i][j];
}
else if(min_max[i][j]>Max)
{
Max=min_max[i][j];
}
}
printf("\nThe minimum sum of degrees of student no. %d is %d",i,Min);
printf("\nThe maximum sum of degrees of student no. %d is %d",i,Max);
getch();
}

Lines
printf("\nThe minimum sum of degrees is %d",i,Min);
printf("\nThe maximum sum of degrees is %d",i,Max);
will print a single value i
, not Min
or Max
. Try this instead:
printf("\nThe minimum sum of degrees for %d is %d",i,Min);
printf("\nThe maximum sum of degrees for %d is %d",i,Max);
Line
min_max[i][j]=sum;
will always have a value of 2 for j
because it is outside the loop for
. Also, I don't understand why you want to store the partial sum of degrees in the min_max array?
