 int a, b, c, S; 
 float A, B, C; 
 cout « "vvedite b,c,S \n"; 
 cin » S » b » c; 
 A = pi - B - C;  // C4700: используется 'B' и 'C'
 b = a*sin(B)/sin(A); // C4700: используется 'a'
 C = a*sin(C)/sin(A); 
 S = a*a*sin(B)*sin(C)/2*sin(A); 
 cout « "b=" « cos(b); 
 cout « "A=" « cos(A); 
 cout « "C=" « cos(C);

First, the quality of the screenshot expects much to be desired. Secondly, if you attach a code, then put a tag with a script on it. Thirdly, VS itself wrote to you all about the error. You are trying to use the value of a variable that has not been given a value. All 3 errors say the same thing.
