Answer to Question #218625 in C for Hemambar

Question

given a matrix of size m×n with values ranges from 100 to 150 . write a C program to generate

0-1 Matrix based on threshold value of 125 . If the matrix element is greater than the threshold set the element to 1 else set the element to 0. print the input Matrix and generate the 0-1 Matrix (use function with 2D array and threshold as arguments)

Sample input:

Input matrix: 120 117 136

110 150 128

135 114 149

Sample output:

0 0 1

0 1 1

1 0 1

#define MX 55
int main()

	int m, n;//size 2d array
	printf("Please enter count rows and cols: (m,n)\n");
	scanf("%i%i", &m, &n);
	int a[MX][MX];//define matrix
	//input matrix element
	for (int i = 0; i < m; i++)
	{
		for (int j = 0; j < n; j++)
			scanf("%i", &a[i][j]);
	}
	//Generate 0-1 array
	int gen[MX][MX];
	for (int i = 0; i < m; i++)
	{
		for (int j = 0; j < n; j++)
			if (a[i][j] > 125)//if greater than threshold
				gen[i][j] = 1;
			else
				gen[i][j] = 0;
	}
	//out genenarted matrix
	for (int i = 0; i < m; i++)
	{
		for (int j = 0; j < n; j++)
			printf("%3d", gen[i][j]);
		printf("\n");
	}
	return 0;
