C code to print or display upper triangular matrix
#include<stdio.h>
int main(){
int a[3][3],i,j;
float determinant=0;
printf("Enter the 9 elements of matrix: ");
for(i=0;i<3;i++)
for(j=0;j<3;j++)
scanf("%d",&a[i][j]);
printf("\nThe matrix is\n");
for(i=0;i<3;i++){
printf("\n");
for(j=0;j<3;j++)
printf("%d\t",a[i][j]);
}
printf("\nSetting zero in upper triangular matrix\n");
for(i=0;i<3;i++){
printf("\n");
for(j=0;j<3;j++)
if(i>=j)
printf("%d\t",a[i][j]);
else
printf("%d\t",0);
}
return 0;
}
Sample output:
Enter the 9 elements of matrix: 1
2
3
4
5
6
7
8
9
The matrix is
1 2 3
4 5 6
7 8 9
Setting zero in upper triangular matrix
1 0 0
4 5 0
7 8 9
