my output for these scores comes out in whole numbers. How do I get it to read out 2 decimal places to the left?Code:#include<stdio.h> //Write a function, invoked from the main function which will allow scanning data into the array. void input(int examscores[5][4]) { int i,j; for(i=0;i<5;i++) { for(j=0;j<4;j++) { printf("input grades of student %d for exam %d\n: ",i+1,j+1); scanf("%d",&examscores[i][j]); } printf("\n\n"); } } //Write a function that will calculate and output the average (to 2 decimal places) //for each student appropriately labeled. void average(int examscores[5][4]) { int i,j; int sum=0; double avg_student; for(i=0;i<5;i++) { printf("Student %d's average score is\n ",i+1); sum=0; for(j=0;j<4;j++) { sum=sum+examscores[i][j]; } avg_student=sum/4; printf("%.2f\n",avg_student); } } //4) Write a function that will calculate and output the average for each of the 4 exams //appropriately labeled. void overall_average(int examscores[5][4]) { int i,j; int sum; double avg; for(j=0;j<4;j++) { printf("\nExam %d Average: ",j+1); sum=0; for(i=0;i<5;i++) { sum=sum+examscores[i][j]; } avg=sum/5; printf("%2f",avg); } } //Write a function that will output the original entry data appropriately labeled. //There should be column headings for the exam number and row labels for the student number as shown: void output(int examscores[5][4]) { int i,j; printf("\n Exam 1 Exam 2 Exam 3 Exam 4"); for(i=0;i<5;i++) { printf("\n%d ",i+1); for(j=0;j<4;j++) { printf("%d \t",examscores[i][j]); } } } int main(void) { //Create a 2 dimensional array (5X4 (int type)) which can hold 4 exam scores for each of 5 students. int examscores[5][4]; input(examscores); average(examscores); printf("\n"); overall_average(examscores); printf("\n"); output(examscores); printf("\n"); getchar(); return 0; }
