Make a fundamental basic note for my C Programming that I am allow to use in the exam room. I know nothing about programming. the note takes one side of A4. I repeat it, I know nothing about programming.

float tada[4][7]={ {3.1,4.6,10.5,9.7,12.9,5.5,23.0}, {11.3,-7.7,12.9,1.1,6.6,80.9,50.5}, {4.4,-2.2,60.5,2.8,7.0,7.0,55.5}, {6.2,-8.2,6.8,2.5,77.1,19.0,5.5},}; int r,c, a; int main() { while(1) { printf("colum.....1\nrow......2\n"); scanf("%d",&a); if(a==1) { printf("choose colum 0 through 6\n"); scanf("%d", &c); for(r=0; r<4; r++) { printf("%f ", tada[r][c]); } } if(a==2) { printf("choose row 0 through 4\n"); scanf("%d", &r); for(c=0; c<7; c++) { printf("%f ", tada[r][c]); } } printf("\n"); } }
