{floatc,l;c=2*r*p;l=2*atan(1/(2*c));returnl;}因为你的函数在声明和实现的时候，参数类型不一致导致的，看了一下，有两处追问#includestdio.h#includemath.hintJ(intc){ints=1,d=1;for(;d=2*c1;d)s=s*d;returns;}voidmain(){intn;doublesin=0,x,eps;printf(\"pleaseinputxandeps:\");scanf(\"%lf%lf\",for(n=0;pow(-1,n)*pow(x,2*n1)/J(n)=eps;n)sin=pow(-1,n)*pow(x,2*n1)/J(n);printf(\"sinx=%lf\",sin);}LINK:fatalerrorLNK1168重写了还是错
