怎样建立网站平台,wordpress筛选模板,创建自己的网址,统计wordpress访问该楼层疑似违规已被系统折叠 隐藏此楼查看此楼解N元一次方程从文件读入整数 N, 然后读入N*( N1)矩阵#xff0c;得到解并输出到文件中。int main(){int ch;printf(\n);printf( Gaussian Matrix Cal \n);printf(\n);printf(Choose:…该楼层疑似违规已被系统折叠 隐藏此楼查看此楼解N元一次方程从文件读入整数 N, 然后读入N*( N1)矩阵得到解并输出到文件中。int main(){int ch;printf(\n);printf( Gaussian Matrix Cal \n);printf(\n);printf(Choose:1.Input Matrix 2.Read Matrix From File\n);printf(Your choice:);scanf(%d,ch);if(ch!1ch!2){printf(Enter Error!!!\n);return 0;}switch(ch) {case 1:printf(Enter a filename to save data:);scanf(%s,filename);if(!InputMatrix()){printf(Not enough memory/Input error!!!\n);return 0;}if(!OuputMatrix()) return 0;break;case 2:printf(Enter The Matrix File Name:);scanf(%s,filename);if(!(fpfopen(filename,rb))){printf(Cannot Open the data file!!!\n);return 0;}if(!ReadMatrix()){printf(Unknown File Format!!!\n);return 0;}break;default:printf(Unexpected Error occured!!);return 0;}if(!GaussCal()){printf(Math error/Not enough Memory!\n);return 0;}if(!Result()){printf(Cannot Create Result File!!!);return 0;}printf(All Done!!!\n);if(fp) fclose(fp);if(out) fclose(out);if(Mat) free(Mat);if(X) free(X);if(buff) free(buff);return 1;}怎吗解释这个程序啊好像没有把解输出到文件中的语句啊帮帮忙拉
