Examples of Using Functions

Assert

used to report internal errors

Code

#include <assert.h>
#include <stdio.h>
 
int main(void) {
	int rows = 0, cols = 0;
	int conversions = scanf("%d %d\n", ), &rows, &cols);
	assert(conversions == 2);
	printf("rows = %d, cols = %d\n", rows, cols);
	return 0;
}

Assertion

Essentially says, “I assert that conversions == 2 is true. Let me know when it is not.”
