编写函数jsValue,它的功能是:求Hofstadter数列中的第m项H(m)(m<1000),结果由函数返回。其中数列H(n)的定义为:H(1)=H(2)=1H(n)=H(n-H(n-1))+H(n-H(n-2))(n>2)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.dat中。例如:当t=997时,函数值为605。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);
