体力劳动强度指数的计算公式I=T*M*S*W*10。其中M的含义是（）
第1题：
下列有关储蓄－投资恒等式正确的有（ ）。 A．I=SB．I=S+(T－G)C．I=S+(M－X)D．I=S+(T－G)+(M－X)E．I=S+(T－X)+(M－G)
第2题：
编写函数，isValue，它的功能是：求以下数列中满足t(K)=1的最小的k，结果由函数返回。其中数列t(n)的定义为：
t(0)=m(m为给定正整数，m＜=300)
t(n+1)=t(n)/2 (当t(n)为偶数时)
或t(n+1)=3*t(n)+1(当t(n)为奇数时)
最后调用函数writeDat()读取50个数据m，分别得出结果且把结果输出到文件out.dar中。
例如：当t=299时，函数值为117。
已知对于m＜=300，结果k不超过300
部分源程序已给出。
请勿改动主函数main()和写函数writeDat()的内容。
include＜stdio. h＞
int jsValue(int m)
{
main ( )
{
int m;
m=300;
printf ("m=%d, k-%d\n", m, jsValue (m));
writeDat ( );
writeDat ( )
{
FILE *in, *out;
int i,m,s;
in= fopen ( "in. dar" , "r" );
ut=f open ( "out. dar" , "w" );
for (i=0; i＜50; i++) {
fscanf (in, "%d", &m);
s=jsValue (m);
printf( "%d\n", s );
fprintf (out, "%d\n" , s );
}
fclose (in)；
fclose (out)；
