Xcode crashes when I clear the console after succesful program execution
I was coding in C and Xcode crashes every time I clear the console (or I rerun the program). The code is the following. #define N 3 #define M 3 int Peak(float a[][M]); int main(int argc, const char * argv[]) { int i, j, k; float matrix[N][M]; printf("\nInitialising [%d][%d] matrix\n", N, M); for(i=0;i<N;i++) for(j=0;j<M;j++) { printf("\nInsert element (%d,%d):\n", i,j); scanf("%f", &matrix[i][j]); } k = Peak(matrix); printf("\nNumber of peaks: %d\n", k); return 0; } int Peak(float a[][M]) { int i, j, varbool, peaks=0; float x; for(i=0;i<N;i++) for(j=0;j<M;j++) { varbool=1; x = a[i][j]/2.0; if(j-1>=0){ if(x<=a[i][j-1]) varbool=0; } else if(j+1<M) { if(x<=a[i][j+1]) varbool=0; } else if(i-1>=0) { if(x<=a[i-1][j]) varbool=0; } else if(i+1<N) { if(x<=a[i+1][j]) varbool=0; } if(varbool) peaks++; } return peaks; } I notice this behavior happens frequently with this kind of C programs. The crash log reports error code 6. I tested on two different macs, mine is a macbook pro 2020 13-inch and get the same behavior.
